MHT CET Physics question

A pure resistive circuit element X when connected to an a.c. supply of peak value 200 V, gives a peak current of 5 A which is in the phase with the voltage. A second circuit element Y, when connected to same a.c. supply also gives the same value of peak current but the current lags behind by . If the series combination of X and Y is connected to the same supply, what will be value of r.m.s. current?

• (A)2.5 ACorrect
• (B)2 A
• (C)1 A
• (D)0 A
