Question
What happens to the current when a circuit breaker trips?
- When a circuit breaker trips, voltage across the circuit becomes zero.
- When a circuit breaker trips, current flowing through the circuit becomes zero.
- When a circuit breaker trips, the entire electrical appliances blow off.
- When a circuit breaker trips, the resistance of the circuit becomes zero.
Hint:
The circuit breaker cuts off the flow of electricity
The correct answer is: When a circuit breaker trips, current flowing through the circuit becomes zero.
The circuit breaker cuts off the flow of electricity in order to prevent your circuits from overheating. If they do overheat, they'll cause damage to your circuits and could lead to an electrical fire.
When a circuit breaker trips, current flowing through the circuit becomes zero.
