Question

Elaine drew an electric circuit diagram that includes a door buzzer. But the current in the circuit is too high based on the parts she chose. Which part can Elaine add to lower the flow of current without changing the operation of the circuit?

a lightbulb

a motor

a resistor

a second battery

Answer 1

Elaine can use a resistor in her circuit to reduce the rate of flow of charge(current), as a resistor resists the flow of charges, so it's amount would be reduced.

In short, Your Answer would be Option C) "A Resistor"

Hope this helps!

Answer 2

Answer: The correct answer is a resistor.

Explanation:

The resistor is defined as an electrical device which opposes the flow of current in the closed electric circuit. Addition of resistor in a close electric circuit decreases the flow of current in the circuit.

A light bulb is a source which produces light..

A motor converts electrical energy into mechanical energy

A battery increase the voltage in the circuit.
