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?

Short Answer

Expert verified

Since humans have the lowest resistance, a large current flows, and the fuse breaks the circuit.

Step by step solution

01

Definition

A circuit breaker is an electric switch that protects a circuit from damage caused by overcurrent/overload or a short circuit.

02

Circuit breaker role in preventing shock hazards

Every time a person is electrocuted, the current in all resistors in the system drops suddenly. This is because it provides an alternative path for current, which causes spikes in the current through the circuit.

This causes the circuit breaker or fuse to break the circuit. We can turn off the power and protect people from electric shock.
