JEE · NEET Previous Year Question
A circuit element X when connected to an a.c. supply of peak voltage 100 V gives a peak current of 5 A which is in phase with the voltage. A second element Y when connected to the same a.c. supply also gives the same value of peak current which lags behind the voltage by . If X and Y are connected in series to the same supply, what will be the rms value of the current in ampere?

Answer: D. Full step-by-step solution below.
- A
- B
- C
- D
Correct answer: D
Solution
(d) Element X should be resistive with R = 20Element Y should be inductive with = 20
When X and Y are connector in series
