Questions & Step-by-Step Solutions

What is the unit of impedance in an AC circuit?
Correct Answer: Ohm
  • Step 1: Understand that impedance is a measure of how much a circuit resists the flow of alternating current (AC).
  • Step 2: Know that the unit used to measure impedance is the Ohm.
  • Step 3: Recognize that Ohm is the same unit used for measuring resistance in both AC and direct current (DC) circuits.
