Alternating Current question

2022 · 29 Jul · Shift 2 · Q51

JEE MainPhysicsAlternating CurrentMCQ+4 / −1
A circuit element X\mathrm{X}X when connected to an a.c. supply of peak voltage 100 V100 \mathrm{~V}100 V gives a peak current of 5 A5 \mathrm{~A}5 A which is in phase with the voltage. A second element Y\mathrm{Y}Y when connected to the same a.c. supply also gives the same value of peak current which lags behind the voltage by π2\frac{\pi}{2}2π​. If X\mathrm{X}X and Y\mathrm{Y}Y are connected in series to the same supply, what will be the rms value of the current in ampere?
