Question
An ac source of angular frequency ω is fed across a resistor R and a capacitor C in series. The current registered is I. If now the frequency of source is changed ω/3 (but maintaining the same voltage), the current in the circuit is found to be halved. Then the ratio of reactant to resistance at the original frequency ω is :
Options
A.
B.
C.
