Question

Switch is always connected to the _____ wire.
a. live
b. neutral
c. ground
d. live and ground

Answer 1

Hint: Switch is an electrical component that checks the flow of current through a circuit. Also, remember that a live wire is a wire through which the current is passing through from a high potential. It is a fragment of household sockets that carries electricity from large-scale power plants.

Complete step by step answer:
A live wire is that which passes current or electricity incessantly to the sockets to which we plug-in appliances. Now, the switches that we allocate to sockets are generally connected to the live wire in the socket. This is to certify that current is sent to the socket only when the user turns on the switch, and as soon as the switch is turned off, no current is supplied to the socket. This is done as a safety precaution to ensure that electricity flows into the terminals of the socket only when required by the user and when the switch is off, there is an open circuit that breaks the flow of electricity to the circuit, make sure that no live current exists in the socket.

Hence, the correct answer is option (A).

Additional information:
- There are a few other safety measures that need to be taken while handling a switch.
- Never touch or repair electrical circuits with damp hands as water doings as a conductor between our body and the circuit and we may experience an electric shock.
- It is always suggested to hold electrical equipment with rubber gloves and goggles and make sure all tools that are used are also insulated.
- Always use an electrical tester to make sure that the equipment is de-energized before handling it. A tester bulb lights whenever it touches a live or a hot wire showing that electricity is flowing over that wire.

Note: The live wire which is connected directly to the generators of the power station, there is a neutral wire, which returns the electricity (flow of current) to the generators by completing the circuit, and then there is the earth wire, which doesn’t carry electricity and is connected to the ground, and provides a fail-safe return path to the current in case of equipment malfunction.
