In a series R-L-C circuit at resonance, the voltages across the resistor and the inductor are 30V and 40V respectively. What is the voltage across the capacitor?

At resonance, The inductive reactance is equal to the capacitive reactance, so the answer is 40

Series R-L-C circuit at resonance.

Voltage across Resistor (VR) = 30V

Voltage across Inductor (VL) = 40V

You’re to find Voltage across Capacitor (VC) = ?

At resonance , XL = XC;
so VL =VC : VC =40

Hope you understand

Xc=XL
So Vc=VL,
The voltage across the capacitor is =40V

at resonance XL= Xc
