In capacitive circuit current leads or lags

WebFeb 10, 2016 · 0. There're two ways to realize why reactive power is negative in a mostly capacitive load. The first one is by using the equation you used, Q = V I sin ( θ v − θ i), the second one is by using Q = I 2 X. As usual, here, V and I stand for the RMS value of voltage and of current. Using the equation Q = V I sin ( θ v − θ i), the factors V ... WebPreface. Preface to the First Edition. Contributors. Contributors to the First Edition. Chapter 1.
