I am simply interested in electrics but at a real beginners level.
Could anyone tell me the following please:
Why does a mains test screwdriver only light up when you touch the live/line/phase cable in a socket or light? Every book tells me the neutral cable is always live too, so why doesn't the screwdriver light up when you touch this one?
Thanks..
