question 18 of 25
which statement describes a resistor in a circuit?
a. it acts as a switch to control the flow of charge in a circuit.
b. it forces positive charge to move against its natural tendency.
c. it stores charge on conductive plates in a circuit.
d. it heats up by opposing the flow of charge through the circuit.

Explanation:

A resistor resists the flow of electric current (charge flow) in a circuit. According to Joule's law, electrical - energy is converted into heat energy when current passes through a resistor due to this resistance. A switch controls current flow, a battery forces charge to move against its natural tendency, and a capacitor stores charge on conductive plates.

Answer:

D. It heats up by opposing the flow of charge through the circuit.
