Question

In an AC circuit with a pure resistor, what is the relationship between current and the applied AC voltage?

Options

• Current is in phase with the applied AC voltage.

• Current is NOT in phase with voltage.

• Current is the peak value of the applied AC voltage.

• Current is the angular speed of the applied AC voltage.

Answer 1

In a pure resistor, current is in phase with the applied AC voltage. Their phasors therefore remain in the same direction.
