  1. Question 1

    Q1. The rms voltage across a resistor is 100 V. What is the peak voltage?

    • A) 70.7 V
    • B) 100 V
    • C) 141.4 V
    • D) 200 V

    Answer: 141.4 V

    Explanation: V_peak = V_rms * sqrt(2) = 100 V * sqrt(2) = 141.4 V. Option A is incorrect because it results from dividing by sqrt(2).
