Alternating Current
7 3 REPRESENTATION OF AC CURRENT AND VOLTAGE
BY ROTATING VECTORS — PHASORS
In the previous section, we learnt that the current through  a resistor is
in phase with the ac voltage But this is not so in the case  of an inductor,
a capacitor or a combination  of these circuit elements
