Q.
The readings of ammeter and voltmeter in the following circuit are respectively
A) $2A,\ 200V$
B) $1.5A,\ 100V$
C) $2.7A,\ 220V$
D) $2.2A,\ 220V$
Explanation
(d) $V = \sqrt{V_{R}^{2} + \left( V_{L} - V_{C} \right)^{2}}$
$\because V_{R} = V\ \because V_{L} = V_{C}$
$\therefore\ $ Reading of voltmeter $= 220V$
Reading of ammeter $I_{rms} = \frac{E_{rms}}{Z}$
$= \frac{220}{100} = 2.2A$
