A) zero
B) \[30{}^\circ \]
C) \[60{}^\circ \]
D) data is incomplete
Correct Answer: C
Solution :
From the relation, \[\tan \theta =\frac{{{X}_{L}}-{{X}_{C}}}{R}\] where \[{{X}_{L}}-{{X}_{C}}\] is the net impedance of the circuit. \[\Rightarrow \] \[\theta ={{\tan }^{-1}}\frac{{{X}_{L}}-{{X}_{C}}}{R}\] \[{{X}_{C}}=0\] \[\Rightarrow \] \[\theta ={{\tan }^{-1}}\frac{\sqrt{3}R}{R}\] \[\Rightarrow \] \[\theta ={{\tan }^{-1}}\sqrt{3}={{60}^{o}}\]You need to login to perform this action.
