In an alternating current circuit consisting of elements in series, the current increases on increasing the frequency of supply. Which of the following elements are likely to constitute the circuit ?

Options

A. Only resistor
B. Resistor and inductor
C. Resistor and capacitor
D. Only inductor

Answer

C

Explanation

Reactance of a capacitor, `X_(C )=(1)/(omegaC)=(1)/(2pi upsilon C)`
As frequency increases, `X_(C )` decreases and therefore current increases. As R does not vary with frequency, therefore, likely elements constituting the circuit may be capacitor and resistor.
