When a capacitor is connected in series LR circuit, the alternating current flowing in the circuit.

When a capacitor is connected in series LR circuit, the alternating current flowing in the circuit.
  1. remains constant.
  2. increases.
  3. increases and then decreases.
  4. decreases.

Solution

Impedance of series LR circuit $Z=\sqrt{R^2+X_L^2}$ When a capacitor is also connected in circuit, Then impedance $Z_L=\sqrt{R^2+\left(X_L-X_C\right)^2}$ Clearly impedance of circuit decreases $\left(Z_2
