Is the dynamic resistance of a diode due to the narrowing and widening of the depletion zone?
So, if a current was flowing through the diode under forward bias and the voltage across the circuit was fluctuating due to a small AC voltage in addition to the DC biasing voltage, the current would experience … Thus, we can say that the resistance of the diode due to the barrier height is increasing or decreasing with time due to the fluctuation of the small AC signal in addition to the DC biasing voltage. …

How to find the power factor of a component when the combined power factor and one other pow... [closed]
Problem:
A 2000 volt-ampere with a power factor of 0.8 lagging is combined with 500 volt-amperes of
synchronous motors. If the overall power factor is 0.9 lagging, find the power factor of the
synchro …
