Question
An alternating voltage whose peak value is 80 volts is connected across a 60 ohms. What is the value of rms current?
Correct Answer
Option B is the correct answer.
Detailed Explanation
First, calculate the RMS voltage (V_rms) from the peak voltage (V_peak): V_rms = V_peak / sqrt(2).Given: V_peak = 80 V.V_rms = 80 V / sqrt(2) ≈ 80 / 1.414 ≈ 56.56 V.Now, use Ohm's Law to find the RMS current (I_rms): I_rms = V_rms / R.Given: R = 60 Ω.I_rms = 56.56 V / 60 Ω ≈ 0.9426 A.
Hint
Remember the relationship between peak and RMS values for alternating current and voltage, and then apply Ohm's Law.
