In the circuit given below, the current through inductor is 0.9 A and through the capacitor is 0.6 A. The current drawn from the a.c. source is (a) 1.5 A (b) 0.9 A (c) 0.6 A (d) 0.3 A

Answer: (d). L and C are in parallel across the source, so they have the same voltage. IL lags V by 90° and IC leads V by 90°: they are 180° apart. I = |IL - IC| = 0.9 - 0.6 = 0.3 A, so the answer is (d).

Parallel AC Circuits

In the circuit given below, the current through inductor is $0.9\text{ A}$ and through the capacitor is $0.6\text{ A}$ . The current drawn from the a.c. source is

Show answer and solution

Answer: (d)

L and C are in parallel across the source, so they have the same voltage.
$I_L$ lags $V$ by $90^\circ$ and $I_C$ leads $V$ by $90^\circ$ : they are $180^\circ$ apart.
$I = |I_L - I_C| = 0.9 - 0.6 = 0.3$ A, so the answer is (d).
