Question

"____" is a term indicating that there is an intentional delay in the tripping action of the circuit breaker, which decreases as the magnitude of the current increases.

a. Adverse time
b. Inverse time
c. Time delay
d. Timed unit

Answer 1

b. Inverse time. Inverse time is a term indicating that there is an intentional delay in the tripping action of the circuit breaker, which decreases as the magnitude of the current increases. It ensures that the circuit breaker quickly disconnects the circuit in the event of a high current fault, protecting the electrical system.

Step-by-step explanation:

The term Inverse time indicates that there is an intentional delay in the tripping action of the circuit breaker, which decreases as the magnitude of the current increases. This means that as the current increases, the tripping time of the circuit breaker decreases. It is called 'inverse time' because there is an inverse relationship between the current magnitude and the tripping time.

For example, if there is a high current flow in the circuit, the time delay of the circuit breaker to trip will be shorter than if there is a low current flow. This helps ensure that the circuit breaker quickly disconnects the circuit in the event of a high current fault, thus protecting the electrical system and preventing damage.
