engineering physics MCQ #255

  1. Question 1

    Q1. The phase difference between voltage and current in a series RC circuit is

    • A) tan^(-1)(ωCR)
    • B) tan^(-1)(1 / (ωCR))
    • C) -tan^(-1)(1 / (ωCR))
    • D) 0

    Answer: -tan^(-1)(1 / (ωCR))

    Explanation: In an RC circuit, current leads voltage, so phase difference is -tan^(-1)(1 / (ωCR)).
