What is RMS value? (& why should we care?) | Alternating currents | Physics | Khan Academy
RMS or root mean square current/voltage of the alternating current/voltage represents the d.c. current/voltage that dissipates the same amount of power as the average power dissipated by the alternating current/voltage. For sinusoidal oscillations, RMS value equals peak value divided by the square root of 2. Khan Academy is a nonprofit ...
