RMS Voltage Calculator

Convert peak voltage to RMS and average values.

Calculated Output

RMS voltage (V) 229.81

Average voltage (V) 206.9

Formula: V_rms = V_peak ÷ √2

Step-by-Step Breakdown

1. Values used:

2. Peak voltage = 325 V

4. RMS voltage = 229.81V

5. Average voltage = 206.9V

The math behind it

For a sine wave, V_rms = V_peak ÷ √2 ≈ 0.707·V_peak; the rectified average is 2V_peak/π.

325 V peak → 230 V RMS (European mains).

Why use RMS?

It gives the same heating effect as an equivalent DC voltage.
