Question : 5 of 54

Marks: +1, -0

In the series L−C−R circuit, the voltage across resistance, capacitance and inductance are 30V each at frequency f=f0.

It the inductor is short-circuited, the voltage across the capacitor will be 30√2V.
If the capacitor is short-circuited, the voltage drop across the inductor will be ‌
30
√2
V.
If the frequency is changed to 2f0, the ratio of reactance of the inductor to that of the capacitor is 4: 1
If the frequency is changed to 2f0, the ratio of the reactance of the inductor to that of the capacitor is 1: 4
