When an AC voltage of 200v is applied across a device X,a current 0.5A flows through the circuit and is in phase with voltage,whan thesame voltage is applied to another device Y, the current flows through the circuit but lags behind the voltage by 90 degree.a)Name the devices X andY.b)Calculate the current flowing through the circuit when the same voltage is applied across the series combination of X abd Y.c) A capacitor blocks dc and allows ac why?
