Energy & Electricity in Science : How Does an Electric Circuit Work?

An electric circuit works by using conductors to carry a current from one place to another after a power supply gives energy to the current. Discover the difference between conductors and insulators, as well as what the best conductors are, with information from a science teacher in this free video on electricity and science lessons.

@busybuzzbuzz it is a placeholder instead of drawing another confusing circuit. as in a guitar amp has a DC power supply and an on off switch, but it also has a lot of complex wiring that would just confuse people learning basic circuts

[MonoMilitiaMusic]

@tbed63 Yes, as in aluminum cans and aluminum foil. He is English and says words with a different accent. "Al um in ee um" is only one example of their different pronunciations

HOW DO YOU MAKE A POTATO GUN!!! plz tell me because i REALLY want to know and i LOVED!!! your video thankyou. plz make a video on how to make a potato gun and send it to me!!! thankyou

@SENTRY000 Actually copper is a better conductor than gold. The reason gold is used on contact points, is because of it's corrosion properties. When gold oxidizes it'd byproduct is only fractionally less conductive than it's origin. Not the case when copper oxidizes. Copper oxide is orders of magnitude less conductive than it's origin state. So a gold contact maintain resistance more consistently. However copper is the better conductor

@tbed63 it's the same metal dude, British people add the extra "I"

@Lightestin

Metal conduct electricity because any substance that requires to conduct electricity needs movable electric

charges . As we know metal contains electron which are movable electric charges so they are able to conduct electricity.

@tbed63

IT IS AN METAL AND IT IS KNOWN FOR ITS CONDUCTING QUALITIES.

What is "Aluminium?" Is that anything like aluminum?

[busybuzzbuzz]

what does he mean "one side off the machine" and "the other side of the machine"?

If you are just starting out in the electrical field videos like this would be a good place to start. Be sure to learn about Ohms Law, Current Flow, Resistance, Voltage, Watts, and other stuff. Without it you will get NO PLACE. You might know how to wire a circuit but if you know nothing about Electrical Law HOW CAN YOU KNOW THE CIRCUIT CAN SAFELY CARRY THE CURRENT WITHOUT BURNING UP? If you know nothing about proper grounding DON'T EXPECT YOUR WORK TO BE SAFE.
