Nettet10. okt. 2024 · The average power when the harmonic distortion is 1% is often referred to as rated output power or maximum useful power, continuous power, undistorted power, etc. Obviously, when the prescribed distortion conditions are different, the rated power value will be different. 2. Maximum output power: When the distortion is not … Nettet26. jan. 2024 · The power in the circuit at any instant in time can be found by multiplying the voltage and current at that instant. Then the power (P), consumed by the circuit is given as P = Vrms Ι cos Φ in watt’s. But since cos Φ = 1 in a purely resistive circuit, the power consumed is simply given as, P = Vrms Ι the same as for Ohm’s Law.

NettetRMS 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, the RMS value equals peak value divided by the square root of 2. Created by Mahesh Shenoy. Sort by:
