Which phasor diagram represents LCR circuit at resonance?

Step-by-step solution

In a series LCR circuit, the voltage across the inductor ( V_L ) leads the current ( I ) by 90^ , while the voltage across the capacitor ( V_C ) lags the current by 90^ . The voltage across the resistor ( V_R ) is in phase with the current. At resonance, the inductive reactance is equal to the capacitive reactance ( X_L = X_C ). Consequently, the voltage across the inductor is equal in magnitude to the voltage across the capacitor ( V_L = V_C ). Since V_L and V_C are 180^ out of phase and equal in magnitude, they c
