Why are fuses and circuit breakers used in circuits?

• Fuses and circuit breakers open to the circuit when a large amount of current flows through the circuit.

• Fuses and circuit breakers increase the efficiency of the appliances within the circuit.

• Fuses and circuit breakers insulate the connection in the circuit.

• Fuses and circuit breakers can help out the electrical consumption.
