Question

controlling the amount of current in a circuit by opposing the flow of charge is a function of which circuit component?
a. resistor
b. transistor
c. capacitor
d. battery

Explanation:

A resistor is a passive two - terminal electrical component that implements electrical resistance as a circuit element. Its main function is to oppose the flow of electric current in a circuit, thereby controlling the amount of current. A transistor is mainly used for amplification or switching of electronic signals. A capacitor stores electrical energy in an electric field. A battery is a source of electrical energy, providing a voltage to drive the current in a circuit.

Answer:

A. Resistor
