In a series LCR circuit the voltage across the resistance, capacitance and inductance is 10 V each. If the capacitance is short circuited, the voltage across the inductance will be
Answer & explanation
Correct answer: option 1
The correct answer is Option 1: $10\sqrt{2} V$
The voltages across all the three components are equal, so the impedance will be the same.
$\Rightarrow R = X_L$
$ I = \frac{V}{\sqrt {R^2+ X_L^2}} = \frac{10}{R\sqrt 2}$
Potential drop across inductor is $V_L = IX_L = \frac{10}{\sqrt 2}$
