The same current is flowing in two AC circuits. The first circuit contains a pure inductor and the second, a capacitor. If the frequency of the AC is increased, then the current will. |
increase in the first but decrease in the second increase in both decrease in both decrease in the first and increase in the second |
decrease in the first and increase in the second |
The correct answer is Option (4) → decrease in the first and increase in the second Inductive reactance $(X_L)∝f$ [f = frequency] Capacitive reactance $(X_C)∝\frac{1}{f}$ [f = frequency] ∴ In the first circuit (inductor), the current decreases as inductive reactance increases due to increase in frequency. In the second circuit (capacitor), the current increases as capacitive reactance decreases due to increase in frequency. |
