A resistance & ideal inductor is connected in the A.C. circuit. Here $V_{1}$ , $V_{2}$ & $V_{3}$ are the readings of the three hotwire ideal voltmeters.

Options:

Answer:

Solution:

Hotwire voltmeters read rms values. For an $L R$ circuit the source voltage is the phasor sum of the voltages across $R$ and $L$ .

$V_{3}^{2} = V_{1}^{2} + V_{2}^{2}$

$V_{3}^{2} < (V_{1} + V_{2})^{2}$

$V_{3} < V_{1} + V_{2}$
