An electrician replaced the switch. The electrician would have received an electric shock unless the circuit was disconnected from the mains supply. Explain why.

Thanks

The switch of what?

If the circuit isn't disconnected, then there's a current flowing.

If someone touches a current, they wouldn't exactly be that happy about it. Heck, they might die. With mains, they very much would have a chance of death, not a very nice prospect imo.
