I was looking at a job practice test and found this problem. What dissipates more heat from a resistor, AC or DC voltage?
Im thinking AC because the voltage is always changing but I don't know for sure.
Both practically the same formula for power
cos theta VI=P=Watt
VI=W
Can someone help me understand this question or is this a trick question?
