Question

Statement I: A fuse is connected in parallel connection in an electric circuit.
Statement II: A fuse wire should be a conductor with a low melting point​.

• A. Statement I is correct and statement II is incorrect.
• B. Statement I is incorrect and statement II is correct.​
• C. Both the statements are correct​.
• D. Both the statements are incorrect.​

Answer 1

The correct option is B Statement I is incorrect and statement II is correct.​

A fuse is a safety device in electrical devices which melts and breaks the electric circuit when the current exceeds the safe limit. To serve this purpose, a fuse wire must:
1. be made up of a conducting material and conduct electricity in the circuit in which it is connected.
2. be chosen such that it has a low melting point so that it melts when an excessive amount of current flows through the fuse wire.
Also, fuses are always connected in series in an electric circuit. When there is an overcurrent in the circuit, the fuse blows out. When a fuse blows out, it opens the circuit and stops current to flow through the circuit components and prevents damage to the electrical components connected in the circuit.
Therefore, statement I is incorrect, and statement II is correct
