An ac source of angular frequency 
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 to 
(but maintaining the same voltage), the current in the circuit is found to be halved. The ratio of reactance to resistance at the original frequency 
will be.
