Question

In view of the small currents that cause shock hazards and the larger currents that circuit breakers and fuses interrupt, how do they play a role in preventing shock hazards?

a) By reducing voltage.

b) By increasing resistance.

c) By interrupting the circuit in case of a fault.

d) Both b and c.

Answer 1

Circuit breakers and fuses prevent shock hazards by interrupting the flow of electricity in case of a fault, such as excessive current flow that could be dangerous.

Step-by-step explanation:

Fuses and circuit breakers are key devices in preventing shock hazards by interrupting the flow of electricity in the event of a fault, such as a short circuit or overload. These safety devices operate by detecting excessive current that could potentially cause harm to humans or start a fire, and they function by opening the circuit to stop the flow of electricity. The correct answer to how they play a role in preventing shock hazards is c) By interrupting the circuit in case of a fault.
