# How does a resistor affect an AC circuit?

Jul 23, 2015

Resistor imposes a restriction on the movement of alternating current the same way it does to a direct current..

#### Explanation:

Value of opposition is the same for a resistor in case of both AC and DC.
It, similar to a circuit carrying direct current opposes an alternating current.
It dissipates power as well.
Ohm's law $V = i R$ is followed as well where the value of the current i = i""_(rms).

Where i""_(rms) is the root mean squared current.
