In an LCR series circuit, if the angular frequency is gradually increased then match the following columns Column I (A) Capacitive reactance (B) Inductive reactance (C) Resistance (D) Total impedance Column II i) will continuously increase ii) will remain constant iii) will first decrease and then increase iv) will continuously decrease

Answer: (A)

Solution

Capacitive reactance decreases continuously as increases, so (A) matches (iv). Inductive reactance increases continuously, so (B) matches (i). Resistance does not depend on frequency and remains constant, so (C) matches (ii). The impedance \sqrtExtra open brace or missing close brace{R^2(X_L$ -
