Answer 2

Answer:

A switch is connected to live wire because neutral wire doesn't have any voltage until it is connected to the live wire. So, it is always better to cut off the supply which is given from the live wire.

therefore,

we know, earth wire is for safety purposes,

neutral wire doesnt have any current,

and so we use the live wire to connect  with the switch.
