# NEET Physics Alternating Current Questions Solved

In a LCR circuit the pd between the terminals of the inductance is 60 V, between the terminals of the capacitor is 30V and that between the terminals of resistance is 40V. the supply voltage will be equal to ……

(1) 50 V

(2) 70 V

(3) 130 V

(4) 10 V

(1) $V=\sqrt{{V}_{R}^{2}+{\left({V}_{L}-{V}_{C}\right)}^{2}}$

$=\sqrt{{\left(40\right)}^{2}+{\left(60-30\right)}^{2}}=50V$
