Question
An a.c circuit has a peak voltage of 100V across a 50Ω resistor. What are the respective peak and r.m.s currents?
Correct Answer
Option D is the correct answer.
Detailed Explanation
I_peak = V_peak / R = 100/50 = 2 A. I_rms = I_peak / √2 = 2 / 1.414 = 1.414 A.
Hint
I_peak = V_peak/R; I_rms = I_peak/√2.
