A) The current leads the driving voltage
B) The driving voltage leads the current.
C) The current and driving voltage are in the same phase.
D) Any of the above may be true depending on the value of resistance
Correct Answer: C
Solution :
[c] In an ac circuit, the ac driving voltage v leads the circuit current i through an angle \[\theta ,\] given by \[\tan \theta =\frac{{{X}_{L}}-{{X}_{C}}}{R}=\frac{0}{R}=0\]\[\Rightarrow \]\[\theta =0\] i.e., the driving voltage and current are in the same phase.You need to login to perform this action.
