Question
For protecting electrical appliances at home
- A circuit breaker is connected in series with house wiring system and a fuse is connected in parallel with house wiring system
- A circuit breaker is connected in parallel with house wiring system and a fuse is connected in series with house wiring system
- A circuit breaker is connected in parallel with house wiring system and a fuse is connected in parallel with house wiring system
- A circuit breaker is connected in series with house wiring system and a fuse is connected in series with house wiring system
Hint:
A circuit breaker is connected in series.
The correct answer is: A circuit breaker is connected in series with house wiring system and a fuse is connected in series with house wiring system
- For protecting electrical appliances at home a circuit breaker is connected in series with house wiring system and a fuse is connected in series with house wiring system.
- If the current going through the fuse is too great then the wire in the fuse melts and breaks the flow of current.
