In series LCR circuit, the voltage across the inductance and the capacitance are not

Options

  1. Aout of phase with the voltage across the resistance by 90^ .
  2. Bequal in magnitude at resonance.
  3. Cout of phase with each other by 180^ .
  4. Din phase with the source voltage.

Correct answer

D. in phase with the source voltage.

Step-by-step solution

In an LCR circuit, the inductor (L) and capacitor (C) introduce phase shifts in the current compared to the source voltage due to their reactive properties. The inductor causes a phase shift of +90 degrees, leading the voltage, while the capacitor causes a phase shift of -90 degrees, lagging the voltage. Thus, voltage across L and C are not in phase with the source voltage.
