ALTERNATORS & BATTERIES | How They Work

Your car battery is really heavy, because it's full of chemistry! Inside, it’s made of Lead and Acid-- That’s why it’s called a LEAD-ACID BATTERY. This episode of Science Garage talks about how batteries work, how alternators work, and how they work together to power your car!
Bart teaches us how cars work by blowing stuff up and cutting things in half. It’s a science show for the car lover who’s easily bored. Join Bart as he explains the science behind everything automotive. This is cars down to the atom. This is Science Garage.
Some of our best videos ever are coming out soon, stay tuned so you won't miss a thing!

They work with electricity right ? On A serious note can you do a video on straight cut gears Im interested in learning how they actually work and Why they whine so high

[@guigui70051]

Mike Arredondo about gearboxes in general

[@ardijanuar2036]

Mike Arredondo watch motive dvd channel, they just released video about manual gearbox in general

[@blacksheep343]

As well as a cvt transmission!!!

[@JohnMiller2]

They whine because the gears are straight cut and not helical cut. Just like the reverse on any car. Rougher and more aggressive gears = whine

[@GETUPANDGO]

I can't stand CVT transmissions, but, would still enjoy learning about them!

[@nohabloemojislosiento4930]

You should do one of these on engine configurations. Such as why we don't use V4 engines anymore, why straight engines have better balance, benefits of flat engines. I think people would find it interesting like I do.

[@jaynichol3743]

Literally how much better school would have been if you were my teacher or I could of learnt so much more and been interested in learning from videos like these! Like I’ve never really thought about learning about car batteries and alternators and now I know and will remember loads about it from you just being a genuinely great teacher from the heart of all things about cars and more! I just guess I’m here to say thanks aha (the cool editing and directing also helps keep me interested but it’s not too much to distract me from the subject of the video) great work donut media

Just watched videos on this topic from both engineering explained and engineerguy. Although they cover aspects about lead acid batteries which your video doesn't, your animated explanation about how the battery actually works is the best imo.

[@Lukeff7]

I have just come across these videos and I like them a lot!!!

[@nicmost3044]

Good teaching. Only mistake is that car alternators regulate the "low" current in the rotor/armature. It's sends the "low" DC current via the slip rings, where more current is given, to the rotor generating a stronger magnetic field, thus making the alternator make more "High" output current. What you described in your vid is a motorcycle alternator. They have a device called a regulator-rectifier that rectifies and then regulates they main "High" output current. The rotor is NOT "low" dc powered in a motorcycle alternator, it has permanent magnets. I like these teaching vids, I can learn a lot from this.
