Question

*Which of the following is the appropriate change when a large amount of current flows through the fuse wire connected to the circuit so as to avoid damage of the electrical appliances in the house?*

1️⃣ The electric current breaks, as the temperature of the fuse wire rises.
2️⃣ The electric current breaks, as the fuse wire melts.
3️⃣ The temperature of fuse wire decreases.
4️⃣ The direction of current changes due to bending of the fuse wire.​

Answer 1

Answer:

1️⃣ The electric current breaks, as the temperature of the fuse wire rises.

2️⃣ The electric current breaks, as the fuse wire melts.

3️⃣ The temperature of fuse wire decreases.

4️⃣ The direction of current changes due to bending of the fuse wire.​

Answer 2

Answer:

The electric current breaks, as the fuse wire melts.

Option number 2 is correct.

Explanation:

Which of the following is the appropriate change when a large amount of current flows through the fuse wire connected to the circuit so as to avoid damage of the electrical appliances in the house?

The electric current breaks, as the fuse wire melts.

• If too much current flows, the fuse wire rises to a higher temperature and melts, thus opening the circuit, but destroying the fuse. A circuit breaker opens a circuit as soon as the current climbs to unsafe levels, and can be used repeatedly.
• Fuses and circuit breakers open or break the circuit automatically when too much current flows through them. When that happens, fuses melt and circuit breakers trip the circuit open. Fuses and circuit breakers are designed to protect conductors and equipment.
• fuse wire is a wire of high resistance and low melting point. when very large current will pass through it, heat will be generated which will melt the fuse wire and break the circuit. By using electric fuses in home we can protect the home appliances from damaging by large amount of current.
