In capacitive circuit current leads or lags
WebThis application note discusses how an oscilloscope furthermore a function generator can be used to do a simple, transparent impedance measurement. Web"Lead" and "Lag" reflect the relative timing of two signals. If func1 has a peak sooner than func2, we say func1 leads func2. In these graphs, time increases as you go to the right. So …
