LEDs are semiconductors, diodes in particular. The current flowing in an LED is an exponential function of voltage across the LED. The important part about that for you is that a small change in...
um.........I don't know.I know something that will more and likely help you.Try googling it.I hope that helps. Or a dictionary or encyclopedia. Or a local library. One of those places will surley...
For an inductive load, the current lags the voltage by 90 degs. Hence the power factor for an inductive load is 0. For a capacitive load, the current leads the voltage by 90 degs. Hence the power...
