What is the peak voltage of an AC source if its RMS voltage is 220 V? (2021)

What is the peak voltage of an AC source if its RMS voltage is 220 V? (2021)

Step 1: Understand that RMS voltage (V_rms) is a way to express the effective voltage of an AC source.
Step 2: Know that the peak voltage (V_peak) is the maximum voltage that the AC source reaches.
Step 3: Remember the formula that relates peak voltage to RMS voltage: V_peak = V_rms × √2.
Step 4: Substitute the given RMS voltage (220 V) into the formula: V_peak = 220 V × √2.
Step 5: Calculate √2, which is approximately 1.414.
Step 6: Multiply 220 V by 1.414 to find the peak voltage: V_peak ≈ 220 V × 1.414.
Step 7: Perform the multiplication: V_peak ≈ 311 V.
