Question

Draw graphs showing variation of inductive reactance and capacitive reactance with the frequency of the applied ac source b. Draw the phasor diagram for a series RC circuit connected to an ac source c. An alternating voltage of 220V is applied across a device X, a current of 0.25 A flows, which lags behind the voltage by a phase difference of π/2. If the same voltage is applied across another device Y, same current flows but now it is in phase with the applied voltage i. name devices X and Y ii. Calculate the current in the circuit when the same voltage is applied across series combination of X and Y (PYQ 2018) [5M]
