Oh, you’ve caught me just after my lab, yaar! That 311V is the peak of the sine wave, calculated as 220V multiplied by √2. RMS, or root mean square, is the equivalent DC voltage that would produce the same heating effect—that’s the 220V we talk about.
But honestly, the theory felt useless last week when our village transformer blew and Papa measured 180V on his old meter. In my father’s shop, the voltage ‘RMS’ just means ‘Really Might Sag’, bhai.
