Question

Fuse or Miniature Circuit Breakers(MCBs) are not used in a circuit containing electric cells. Why?

Answer 1

Answer:

Fuse wires or miniature circuit breakers are not used in a circuit containing electric cells because a dry cell does not has a high amount of voltage and there is no danger.

Answer 2

Answer:

The electrical cell does not cause the flow of electricity with high voltage. MCBs are used when the flow of electricity is high. Hence, MCBs are not used in electrical cells or batteries.
