Hi, how the real power heating current will be a for a pwm signal will be mesured in average? TrueVrms? Or will be the same like normal current. The singal is 0 to 5v. Not negative value, so is more like pulseing dc. For example, two led vf=2v connected to 9v 250ohms with a frequency of 10%hz at 50% duty cycle. What would be the true current? Another examples is when I have a buzzer about 2khz at 50% when mesured direct normal dc current is 120ma, average is about 80ma. Thank you.
