Complete the sentence:
The advantage of a circuit breaker over a fuse is that
- It is replicable as well as can be used again and again.
- It can be reset as well as used again and again.
- It cannot be reset and used over and over.
- It cannot be used over and over.
Hint:
Circuit breaker protects from damage caused by the flow of excessive current
The correct answer is: It is replicable as well as can be used again and again.
The advantage of a circuit breaker over a fuse is that It is replicable as well as can be used again and again
It protects from damage caused by the flow of excessive current. It is more reliable. It can be reset as it operates via a switch. It is very sensitive in operations.
