i 0 = V 0 / R----( 9)

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
