Question

why switch is always connected with a positive wire​

Answer 1

Hi mate

Because 'earth' is always connected there is nothing to be gained by switching off neutral, except that this would break the load connection and stop the powered device. Switching the 'live' wire isolates the device from the power source. Not only does it stop the device it removes the power connection.

Hope it helps you..

Thanks for asking and keep asking more ✌✌

Answer 2

Answer:

switch in the electrical circuit is always connected to the live wire so that the socket/appliance is not live when it is switched off. A fuse is usually a thin piece of wire that will melt and break the circuit if too large a current flows through it.
