Inductors are everywhere, from power supplies and filters to transformers and even your smartphone. But what exactly is an ...

We can do this by using a switch. A doorbell is a switch that completes a circuit ... we use work. From remote-controlled cars to electric cars we can actually drive. In this game, touching ...

Because they're safety devices, circuit breakers have to work automatically. (Of course, you can also operate them manually, which you should always do when doing DIY electrical work.) Here are ...

How do you get ... so I'll send electricity round the rope,and when it passes through your motor, what happens?I spin! Whee! So, Greg, that circuit that we made, would that work in real life?

To the uninitiated, electricity might seem like ... redirecting water or gusts of wind to do the spinning. Solar panels, meanwhile, work differently because they don’t need moving magnets ...

it’s important to understand how superconducting materials work. A superconductor is any material that conducts electricity without offering any resistance to the flow of the electric current.
