Smaller Battery = BRIGHTER Light?!!! -

This is Quint BUILDs entry for the #VeritasiumContest. Contest details: www.veritasium.com/contest
In case it wasn't clear from the video, the smaller battery has a higher voltage, but that just means the bulb will "eat" through it even faster than if it were the same voltage as the larger battery.
Key takeaways:
- Higher voltage (V) pushes more current (I) thru the same bulb (V=IR or I=V/R, Ohm's law).
- The smaller battery is a stack of many tiny sandwiches (higher voltage) which gets "eaten" very quickly.
- Current always completes a circuit to ground (bulb was pooping ground symbols).
Not covered:
- Battery capacity is rated in amp-hours, but this is not a measure of power or energy.
- Power=Volts x Current (watts), Energy=Power x Time (watt-hours)
- Battery chemistry (Alkaline vs. Nickel or Lithium) affects battery capacity significantly.
- Cheap battery brands often lie about capacity, so buyer beware!
- Batteries often don't include rated capacity on the label. Rather they publish runtime charts under various conditions on their websites.
Derek is a man after my own heart, exploring and sharing, even when the results are controversial. What a cool way to capitalize on his bet, generating a surge of short STEM videos online!
What do you think, should I do more videos like this one? It was a lot of work cramming that much information into 60 seconds but I enjoyed every moment!

Fantastic explanation. The 'excretion' of the ground symbol was so wonderfully unnecessary, but i literally LOL'ed. Well done sir.

[@enquiryplay]

You even managed to squeeze in a PSA about the dangers of consuming batteries - Well done!

[@fernandomarsalcaldera6158]

What an amazing video, and all the information is condensed in 60 seconds with a hilarious edition. Congratulations for this masterpiece.

[@mikeseeley1316]

Good luck with the contest Quint. I really enjoy your content

[@Zickzag]

This is truly a great and simple explanation. Thank you so much.

[@ruthlessrubberducky5729]

That's a good way of explaining it. Brilliantly simple. I'm glad the internet discovered you from your knife bot. I'm excited to see future projects and helpful mental models!

[@jamesflynn7054]

Awesome explanation, best of luck!

[@FredHsu]

Brilliant illustration

[@najeebullah1155]

This video makes so much easy to understand volt and Amps relation

[@RubikRocksMinecraft]

I LOVED this video. You should definitely do more 😃 not only funny, but super informative. I’ll be sharing this with my old high school physics teacher, he will get a kick out of it.

[@hoodio]

the sandwich analogy is great haha

[@UyeGaming]

Gl in the contest!!

[@mr2octavio]

Great video Quint

[@joyalgeorge5651]

Great explanation and animation

[@theBabyDead]

Ton of info in a short amount of time. Well done, good sir.

[@Ryan-lk4pu]

Fingers crossed for you, mate!

[@integrando1847]

good, i dont know who will choose veritasium as the champion with a lot of excellente videos

[@teslatrooper]

The little earth symbol poops are great, good luck with the contest.

[@TheSockMonkeyGuy]

Excellent explanation! And I chuckled at seeing the tiny brain in the skull when trying to eat the battery... 🤣

[@QuintBUILDs]

Ha you noticed! 👍 I swear some days my brain can't be much bigger than I drew it! 🤣

[@TheSockMonkeyGuy]

@@QuintBUILDs That gives me a gag idea for a future sock monkey video where a fluoroscope could slide in front of me showing my head full of fluff. Not sure where I can use that, but I'll file it away for future reference... 😆

[@alexantrim9528]

@@QuintBUILDs If that's the size of your brain, I wonder how small mine is...

[@QuintBUILDs]

My shortest video EVER! If you haven't heard, Derek from Veritasium started a contest for the best 60 second (or less) STEM video. Contest details: www.veritasium.com/contest This is my entry, but I need LIKES so please thumbs up the video. If you think I should do more of these as opposed to the 15-20 minute videos, let me know in the comments. In case it wasn't clear from the video, the smaller battery has a higher voltage, but that just means the bulb will "eat" through it even faster than if it were the same voltage as the larger battery. Key takeaways: - Higher voltage (V) pushes more current (I) thru the same resistive load of a bulb (R) (V=IR or I=V/R, Ohm's law). - The smaller battery is a stack of many tiny chemical sandwiches (higher voltage) which gets "eaten" very quickly. - Current always completes a circuit to ground (bulb was pooping ground symbols).

Love the vid. Thx!

[@1123pawel]

Great video, thank you for sharing.

[@TankYou90]

I was on my way to make a battery sandwich when I saw this

[@beaubatten2475]

Great video, seems potentially misleading however, the sandwiches "end to end" look a lot like they're connected in series, while "stacked up" looks like parallel, however in truth this works the opposite way around where series increases voltage and parallel increases capacity, I think without specifying what these are meant to represent a lot of people would assume the wrong configuration

[@pbryan]

I can never unsee ground poop!

[@QuintBUILDs]

Ha ha, me too!

[@8manticoreXbaricos8]

man i went through college, but this is the best explanation

[@travismoore7849]

You can take a 8.4v rechargeable battery and charge it up a bit with a solar panel. Even if it is 3v or so and can run a led that is fine. A variable resistors could cut the volts down to run an led. Once the led no longer runs with 0 resistance you can light it with a single cell in series with the battery. But you can also use a capacitor that is zapped with electrostatic energy at 3500uf at 36v or so.

[@NicksStuff]

It's really cute but that should go to Quint kindergarten or something

[@herzogsbuick]

fantastic!

[@matejgamingandotherstuff6484]

The small one has 6 tiny cells but the big one has 4 big cells. Hence the lower voltage of the big one. Both batteries have 1.5v cells

[@Trebseig]

The 9V battery can also be opened. Some contain 6 small separate cells! (others 6 messy layers of chemical uhw)

[@lasersbee]

A bigger battery is only a bigger barrel... in the case of the barrel it can hold more water.

[@ClosestNearUtopia]

As a electrician I dont follow any of what you just told.. See voltage more like a pressure, its (basically said) always there but the Current - Amps, doesnt have to flow.. So amps hour, basically can tell you how long a cetrain load can be used until the battery has drained an no pressure is left to create a flow, in this case electrons, traveling from negative to positive, and measured in hours. Use the resistance of the component and the voltage to calculate the amps drawn by the system. If that is 1 amp and you got an 500Ah battery, thets gonna be about 500hours of fun.

[@QuintBUILDs]

That all makes sense to me. Sorry the content didn't click for ya. To my eye it follows what you wrote with the addition of what additional pressure does to a resistive load. I'll try harder next time. :)

[@ClosestNearUtopia]

@@QuintBUILDs that is ok, I often see people trying to explain electricity and some make sense, some dont and some dont even are right. I tried watching your video a few times more, and it quite makes sense altough only on batteries? Since ac is used in many ways and dc is quite straight forward I prefer thinking in power, which can be compared to kinetic impact(speed*mass=power). I like to do that for ecpecially the later stages in the learning, where you will convert this available power into different voltage or maybe amps more depending on your application. Fun fact: I once worked in an chromery plant. We had a 13Vdc 18kA power rail system to chrome the rolls for cold rolling steel into plate rolls. We actuall sat on this power rail just because it was there, all unisolated running along the wall.. The only thing you had to make sure of is that you dont short out the rails on top of each other with something metal, it will weld instant. But you could touch both rails with your hands if you liked xD Also 90% of my now colleagues still wont accept how I survived that.. which tells something about their knowledge.. moral: current isnt the harm, voltage is.⚡️

[@ClosestNearUtopia]

@@QuintBUILDs also you did kinda fine man, some people did get your story. May help them later on if they are dedicated to look into it. Also at least you did not say wattage🤢 keep up!

Shocking,love from England.🌩️

[@lynn5655]

Ha, ha! I see what you did there.

[@bogumilpiotrowski]

I feel pain in my teeth during these mark ups

[@fortun8diamond]

9v vs 6v. of course the bigger one will power the bulb longer 40x.

[@drugansltd4344]

Even my 6 year old would understand it, brilliant, you should do kids courses haha

[@FuzzyWCTX]

6 volt vs 9 volt in the beginning of the video?

[@brandondaniel47]

What type of engineer are you. What courses did you take?

[@QuintBUILDs]

look for a video on my background on my smaller channel BUILD2

[@karlstenator]

So a 6v battery is 6 sandwiches stacked high, and a 9v battery is 9 sandwiches stacked. Do amps represent the amount of sriracha sauce chili sauce on each sandwich?

[@Nightykk]

Am guessing KZbin's algorithm changed at some point during the last 3 months, eh? From 500.000-mill+ views, to.. 15-30k. Ouch.

[@akhtarkh]

Sandwich analogy is misleading

[@QuintBUILDs]

How so?

[@whatisit5634]

Hello!! 👋👋

[@MRmisteronwzz]

Has a comprehensive understanding of physics, yet writes 'thru' in his video description instead of through....

[@QuintBUILDs]

Not that anyone cares, but it's common on engineering drawings to minimize clutter. Reference www.eng-tips.com/viewthread.cfm?qid=257193 Fun fact: I'm certified "thru" ASME at a senior level in their "GD&T" standard so I kinda can't help typing it. I started my first KZbin channel teaching that standard for free.

[@3mar00ss6]

the sandwich analogy was so misleading, a small capacity high voltage battery should have to sandwiches stacked on top of each other, while a high capacity battery should have 4 stacked next to each other ( ಠ ▵ ಠ)...

[@shreyasp3287]

Ha😂

[@_Everyone__]

I know you target people who done know anything at all about science, like small kids ...but you shouldn't talk down to people like that, it's half gibberish, and still without answering the videos question. Not that I need the answer, but I was curious how it would be presented, and it's made for dummies without explaining much anyway.

[@QuintBUILDs]

Sorry you feel that way. If you read the other comments I think you'll agree you're not in the majority.
