Great video! Could somebody explain how the circuit is formed for the bulb to light up?! The explanation is often more important than the answer itself. Tks,

[@mY_m0M_ThREw_mE_t0_mARz]

Well the circuit is just copper wire and hold it the way he is showing in the video

thank you for letting me pass for my science project

[@alexthebest1401]

If the battery is bigger, are you able to power a larger bulb

[@CrypticMiind21]

Alex Andersen yes but we have to know the voltage battery can handle so according to it we can light it up

[@vibescom-fz4cs]

Alex Andersen you need a smaller light bulb to work or a led light

[@J0sh00]

Funny enough I'm trying to check if a light bulb works and you are using the same exact bulb that I'm trying to check. Thanks for the video haha

[@jivey7337]

Are their any other batteries that work with this

[@doneupp0070]

This video is very useful visually I can see wich ones the positive output and which ones the negative thank you

[@jensenmacneil6914]

Hey! Thanks for the help! Can you explain why we dont feel a shock when touching the bare wire?

[@rhettallain]

If you are using a D-cell battery (1.5 volts), that's not a shock. The wire gets hot if you have the wire going from one end of the battery to the other (this is called a short)

[@jensenmacneil6914]

@@rhettallain Why don't we feel the electricity while holding the wires and lightbulb?

[@jensenmacneil6914]

Is the voltage not high enough in the battery? Is it because the wire is a better conductor? Plz help were presenting in 2 mins

[@rhettallain]

@@jensenmacneil6914 it's both. When you get shocked, you mostly feel the electric current. With 1.5 volts, the current is super low. Also, if you are holding onto a wire, then most of the current goes through the wire and not your body.

[@itsfootballer503]

thank you so much! this helped me a lot with my 8th grade science fair project 3 years ago!

[@krishnarohit5304]

Why don't you get a small shock? Is it because the voltage is too low and you cannot feel it ?

[@shaikhrazzak954]

I dont have a small bulb i dont have wire but i have the battery what should i do with out wire and small bulb???

What’s stopping the bulb filament form blowing instantly if it is rated at 2v shouldn’t it need a resistor

Can someone answer if it's one battery per light bulb could I do a row of lights using wire connectors and the shells of watch cells ?

Thanks for this video,this help me to make decoration of cage. And I think this is easier trick but I have question ❓ can I use this circuit method in fairy lights circuit can it work it? I hope it work.if you have other solution please suggest me because I have buy electric fairy lights...

[@garimasachan6091]

#1 Can we do the opposite? In which bulb is on the negative terminal and the wire one the positive terminal

[@rhettallain]

yup - that still works. You should try it though.

[@oliverwilson5202]

Will this work the same way for running say a 60 to 100w lightbulb?

[@kristinarae536]

can we do it with any light bulb?

will other metals work

where can we get a copper wire

Woah this help's me alot! Thank you so much ! And its already 2020 And I was born 2011.BUt this help's me alot I will watch this many time's!

[@AleighaxRodrickHeffley]

just a question does this shock you?

[@rhettallain]

no. you can't get shocked from a D cell battery. However, if you have the wire going from positive to negative terminal without a light bulb, the wire can get hot.

[@vijayamalan7041]

That batery is how many volt

[@CloutzyDan]

Where my online school gang at?

[@TheRealSlimSigma]

Will galvanised wire work? Steel/iron

[@rhettallain]

that should work. Anything that conducts electrical current should be fine.

[@jilathoudam6104]

Can I use every day company battery

[@rhettallain]

any 1.5 volt battery should work - D Cell, C Cell, AA, AAA. Don't use a 9volt, it will probably break the light bulb

[@Dashport-ih7ww]

Can i use foil instead of wires ?

that should work

[@Voltron4ev4]

Can anyone tell me why the third set up did not work please? Is it because the current cannot branch at the point of contact with the bulb? Thanks.

[@katiemuncil8684]

Who's class are you in

[@TheRealAmek]

Why can’t I use tin foil?

[@petermurphy5302]

If the bulb is 2.47 volts, then does it not need a 2.5 volt battery? I just googled 'C' batteries and they are 1.5v. So how come the bulb lights up?

[@rhettallain]

If the bulb is rated at 2.47 volts, that is the voltage for the optimal brightness. I will have current going through it at any lower voltage - but it might not be very bright.

[@petermurphy5302]

@@rhettallain I see! 'Lightbulb moment' haha. Thanks for your reply

[@kristinarae536]

and can we do it with any battery?

[@rhettallain]

I would recommend any 1.5 volt battery (so AAA, AA, C, D) - but not a 9volt battery and not one of those button cell batteries. As for the lightbulb - this is one of those tiny incandescent bulbs (not LED). You can find these at a hobby store or in one of those cheap flashlights.

is that a battery or an electric cell??

So today we were doing a lab in science with these and we supposed to light up the light. We were also allowed to do an extra thing. some kid did his braces and it somehow worked so what I did was put it in my iPad charger port and what happens next is the iPad just blinks black and white it looked like a barcode my iPad was REALLY fucked up. It still doesn’t work.

Hey everyone.I have five bulbs. All of them are connected by the same wire but when one of them is glowing non of the others should glow even if the switch is pressed. Its for buzzer in a quiz competition. I would be very grateful if u help.

[@mhvdm]

Doesn't light up? I've tried both 1.5V and 9V And none of them lit up the bulb

[@astrocraft6942]

Yeah me too

[@Baohuluxiake]

I tried to connect this way with a mini LED light instead of a flashlight bulb, but the light won't light up, why?

[@lilvipa1]

Check voltage of bulb. Hes using 1.5v battery with 2.4v bulb. If your bulbs voltage is too high, it won't create enough heat is light from battery. I did this with 9v battery and the bulb got way too hot.

[@Baohuluxiake]
