In a series LCR circuit, the voltage across resistance, capacitance and inductance is 10 V each. If the capacitor is removed, the voltage across the inductance will be-

A

10 V

B

102V10\sqrt{2}V

C

102V\frac{10}{\sqrt{2}}V

D

20 V

Answer

102V\frac{10}{\sqrt{2}}V

Explanation

Solution

VR = VL = VC = 10 V

Ž Vsupply = 10 volt & R = XL

After removing capacitor

Vsupply = VR2+VL2\sqrt{V_{R}^{2} + V_{L}^{2}} \ VR = VL

Ž VL = 102\frac{10}{\sqrt{2}} volt
