Question

Fuse is the weakest part of the circuit which melts and breaks the electric circuit in case of an overload.

• A. True
• B. False

Answer 1

The correct option is A True

Explanation:

1. Overloading is the situation where the circuit draws a large amount of current from the mains, causing heating of the connecting wires and circuit.
2. An electric fuse is a safety device that prevents electric hazards.
3. The fuse has a special wire, the melting point of which is lower than the metals which are used to make the conducting wires.
4. Fuse is a piece of a wire of material with a very low melting point.
5. When a high current flows through the circuit due to an overloading or short circuit, the wire gets heated up and melts.

Hence, the given statement is true.
