A resistor and a capacitor are connected in series with a sine wave generator having frequency suchthat the resistance and the capacitive reactance are same i.e. voltage across capacitance, $$V_c$$ is equal to Voltage across Resistance, $$V_R$$. If the frequency ofthe sine wave generator is doubled, then
