Phasor Diagram Of Capacitor. In the above figure we observed that at 0 0 the charging current is at its maximum value because the voltage is increasing slowly in positive direction. V c frac i ωc 90 o the voltage drop in the resistor will be in phase with current in the case of the capacitor the current will leads to voltage drop and for the inductor the current of the inductor will be lag from the voltage drop in the inductor.

The same thing is represented with the phasor diagram. The red colour shows current blue colour is for voltage curve and the pink colour indicates a power curve in the above waveform. It is sometimes helpful to treat the phase as if it defined a vector in a plane.
The vector diagram is drawn starting with a horizontal line representing the current vector i which is the common quantity.
The circuit vector phasor diagram for a series lc circuit is shown in figure 2 and is constructed as follows. The phasor diagram of the capacitor start motor is shown below. It is sometimes helpful to treat the phase as if it defined a vector in a plane. The vector diagram is drawn starting with a horizontal line representing the current vector i which is the common quantity.
