Question

When live wire and neutral wire come in direct contact, it leads to

• A. Short-circuiting
• B. Earthing
• C. Stoppage of electric current
• D. None of these

Answer 1

The correct option is A

Short-circuiting

Step 1: Function of live and neutral wires

• The live wire supplies the current that is delivered to us from the power station.
• The voltage supplied is $220\mathrm{V}$.
• The neutral wire provides a return path of the electricity once it passes through an electric device.

Step 2: Short-circuit

• When current passes through a pathway that was unintended this situation is known as a short circuit.
• When live and neutral wires come in contact, all the electricity passes through that point of contact and the electricity does not flow further.

Step 3: Earthing

• Earthing is the process of connecting the body of an electrical device to the earth wire so that if excess electricity is flowing through the body, then it finds a path through the earth wire to the ground.
• Earthing is done so that if a person touches the electrified body, the current will not flow through the person.

From the above explanations, it can be seen that short-circuiting occurs when live wire and neutral wire come in direct contact.

So, option (A) is correct
