Pure capacitive circuit: capacitor voltage lags capacitor
current by 90o
pure capacitive circuit waveforms. plz plot the wave form
b/w current &voltage.
Remember, the current through a capacitor is a reaction
against the change in voltage across it. Therefore, the
instantaneous current is zero whenever the instantaneous
voltage is at a peak (zero change, or level slope, on the
voltage sine wave), and the instantaneous current is at a
peak wherever the instantaneous voltage is at maximum
change (the points of steepest slope on the voltage wave,
where it crosses the zero line). This results in a voltage
wave that is -90o out of phase with the current wave.
Looking at the graph, the current wave seems to have
a “head start” on the voltage wave; the current “leads” the
voltage, and the voltage “lags” behind the current.
