An inductor, a re
The reactance of an inductor is given by , where f = frequency, L = inductance.
Hence, if the frequency is increased, the reactance of the inductor also increases. Therefore, option (A) is correct. (Ans)
The resistance remains unchanged with change in frequency. Hence, option (B) is incorrect.
The reactance of a capacitor is given by , where f = frequency, C = capacitance.
Hence, if the frequency increases, the reactance of the capacitor decreases. Hence, option (C) is incorrect.
Now, the reactance of the circuit is given by
Since on increasing the frequency, XL increases but XC decreases, their overall difference, that is reactance of the circuit, also increases. Hence option (D) is also correct. (Ans)
