Q.
In the figure shown, three AC voltmeters are connected. At resonance,
A) $V_{2} = 0$
B) $V_{1} = 0$
C) $V_{3} = 0$
D) $V_{1} = V_{2} \neq 0$
Explanation
(a) At resonance, $V_{L}$ and $V_{C}$ are equal in magnitude but have phase difference of $180{^\circ}$ relative to each other
$\therefore V_{LC} = V_{L} - V_{C} = 0$
Hence, voltmeter $V_{2}$ read 0 volt
