In an a.c. circuit, if the frequency is doubled, what happens to the capacitive reactance ( Xc) and the current ( I)? (a) Xc is halved and I is doubled (b) Xc is doubled, I is halved (c) Both Xc and I are halved (d) Both Xc and I are doubled

Answer: (a). XC = (1)/(2π fC) ∝ 1/f: doubling f halves XC. I = V/XC: halving XC doubles I. So the answer is (a).
