- B.The maximum voltage in one cycle
- C.The average power consumed
- D.The resistance in the circuit
Model answer
What a good answer should say
- The number of cycles per second
Explanation
Why this works
Frequency measures how many complete cycles occur in one second, which is vital for understanding the behavior of AC systems. This evidence indicates how quickly the current alternates, affecting the performance of devices powered by AC.
Therefore, frequency is a key parameter in AC circuit design.
