Question

How is a switch connected in a circuit

Answer 1

after the switch is made on , current flow takes place through the live wire as well as neutral wire … Closed switch offer short path to the circuit so the voltage across the switch is 0 and open switch create open circuit so the voltage across the open switch is equal to the supply voltage..

Answer 2

Explanation:

The switch must be placed in live wire to maintain the body of appliance at zero potential in the switch off position and if the switch is kept in neutral wire, then the body of the appliance to keep the body at infinite potential in the switch on position
