[SOLVED] Average power and diodes. Hi, I have this question. If a diode were connected to a circuit with an alternating current and there was a resistor was connected to it, will the average power change? For example, if we take the following values, V max = 6.0 V Resistance = 100 ohms, the Average power will be 0.18 W and the max power 0.36W. When we plot the graph with respect to power dissipated by the resistor with a diode connected, we get a sinusoidal graph with it's second half cycle at a null value and it's first half at a peak value of 3.6W (assuming that the diode is forward biased at the start). I'm not very sure how to calculate max power using graphs; but is the average power still 0.18W? I thank you for your help in advance.
