RMS Value of a Sine Wave Electrical Academia

WebSo, let's assume a 1 ohm load resistor (for mathematical convenience) and square the full wave RMS voltage to get power: - Power = \$ \frac {V^2} 2 \$ and half this power (half wave rectifier) is \$ \frac {V^2} 4 \$. So convert back to RMS voltage by taking the square root and you get the RMS value for half wave rectified voltage is \$ \frac V ... WebFeb 10, 2024 · The remaining parameters were left at the default values. Finally I simulated the model for 0.08 s (4 cycles). Since the sine wave has an amplitude of 10 V, the theoretical RMS value is the amplitude divided by the square root of 2, which yields 7.07 V. The readings obtained from the scope confirm this value (purple line).
