Same current is flowing in two different a.c. circuits. First circuit contains only inductance and second contains only capacitance. If the frequency of a.c. is increased in both circuits, the current will (a) increase in the first circuit and decrease in second. (b) increase in both circuits. (c) decrease in both circuits. (d) decrease in first circuit and increase in second.

Answer: (d). Inductor: I = (V)/(2π f L), so I decreases as f increases. Capacitor: I = V(2π f C), so I increases as f increases. So the answer is (d): decreases in the first circuit and increases in the second.

Same current is flowing in two different a.c. circuits. First circuit contains only inductance and second contains only capacitance. If the frequency of a.c. is increased in both circuits, the current will

Show answer and solution

Answer: (d)

Inductor: $I = \frac{V}{2\pi f L}$ , so $I$ decreases as $f$ increases.
Capacitor: $I = V(2\pi f C)$ , so $I$ increases as $f$ increases.
So the answer is (d): decreases in the first circuit and increases in the second.
