And so your prediction is. . . ?

My analogy may not have been apt, but fact is that you don`t have an inductor without phase shift. The current lags the voltage in an inductor. My dictionary says that phase is a particular stage or point of adbvancement in a cycle; the fractional part of the period through which the time has advanced, measured from some arbitrary origin. Apply a voltage or the voltage across the inductance. Current does not change instantaneously in an inductance, but it lags the imposed voltage change. Lag is to move slowly or fall behind. In a circuit containing resistance and inductance, almost all real world circuits, current lags the voltage. This is phase shift by definition. We correct power factor to overcome phase lag and to eliminate the excess current and loss from the inductive charging and discharging current of an inductive circuit. Reactance only stores energy and does no useful work. I reiterate the accuracy of my postings in this thread, and indeed, inductance and phase shift are inseparable. Please note that inductance can be neutralized with capacitance. Best regards, Richard Harrison, KB5WZI |
