A 15microfarad capacitor is connected to a 220V, 50Hz source. Find the capacitive reactance and current (rmsand peak) in the circuit. If frequency is doubled, what happens to capacitive reactance and current? Share with your friends Share 21 Vara answered this Capacitive reactance:xc=12πfC =12π×50×15×10-6 =212.2 ohmsrms current:Irms=Vxc =220212.2 =1.04 APeak current:Ipeak=2Irms =2×1.04 =1.47 AOn doubling the frequency:Capacitive reactance is inversely proportional to --Becomes halfCurrent is directly proportional to capacitive reactance--Becomes double 71 View Full Answer Boopesh S answered this 1/2*3.14*f*c where c is capacitance and f is frequency. if f becomes doubled then reactance is halved and current is doubled 5
