    Explain to me Electromagnetic Induction, EMF to be exact...

    Hello, I am struggling to understand how electricity is generated in an AC generator... I know that there is a coil of wire and a magnet, and both of them have their own magnetic fields and as the magnet moves into the coil's magnetic field, it causes electrons to move in that coil. Well if that...

    Why does Electricity need a closed circuit?

    Why does Electricity need a closed circuit for the current to flow? Especially in AC where electrons are just pushed back and forth... Wouldn't there be current generated in a wire that's moved through a magnetic field? Why cant there be current until the break of the circuit? you know...

    Intro ( before my account is closed)

    Stupid question about RCDs

    If we have a double pole RCD which is, let's say 30mA 80A, will it trip in an overload situation above 80A in a similar manner to an 80A incomer? Or is it just 'rated' at 80A in the same way a switch may be rated at 6A or whatever? I'm sure it's a dumb question that I should know the answer to...
