MHT CET · Physics · Alternating Current
When a capacitor is connected in series LR circuit, the alternating current flowing in the circuit
- A remains constant
- B increases
- C decreases
- D is zero
Answer & Solution
Correct Answer
(B) increases
Step-by-step Solution
Detailed explanation
The impedance of an LR circuit is \(Z_{LR} = \sqrt{R^2 + X_L^2}\). When a capacitor is connected in series, the impedance becomes \(Z_{LCR} = \sqrt{R^2 + (X_L - X_C)^2}\).
