Question

The electrical switches are put in the

• A. live wire
• B. earth wire
• C. neutral wire
• D. None of these.

Answer 1

The correct option is A

live wire

Explanation for correct option:

1. All the wiring will be done in parallel as the resistance becomes minimum and voltage maximum.
2. The switches are connected in live wire so that when the appliance is turned off, the current will not flow.

Explanation for incorrect options:

1. Switches are not connected to neutral wire because there is no current flowing to the appliance and so will not work.
2. Switches cannot be even connected to earth wire because the earth wire is used to transfer excess current to the earth for protecting against electric shock.

Hence, option A is the correct answer.
