A) \[0{}^\circ \]
B) \[90{}^\circ \]
C) \[30{}^\circ \]
D) \[60{}^\circ \]
Correct Answer: A
Solution :
The phase difference between the applied voltage and the current in the series L-C-R AC circuit is given by \[\tan \phi =\frac{{{V}_{L}}-{{V}_{C}}}{R}\] \[\tan \phi =\frac{30-30}{R}=0\] \[\phi =0{}^\circ \] Therefore, phase angle\[\phi =0{}^\circ \]You need to login to perform this action.
