उत्तर
A switch in a circuit is always connected in the live wire.
Explanation:
A switch must be connected to the live wire so that switching it off disconnects the appliance from the live supply. A switch in the neutral wire can leave the appliance connected to the live wire, creating a risk of electric shock.
