From instantaneous values of alternating voltage and current , we can conclude that in pure resistor , the current is always in phase with applied voltage Their relationship is graphically represented as
A
. C through pure inductor

Figure below shows the circuit in which voltage source V = V 0 sinωt ( 10 ) is applied to pure inductor ( zero resistance ) coil of inductance L
�
As the current through the inductor varies and opposing induced emf is generated in it and is given by -Ldi / dt
