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?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Element X should be resistive with R = 20 
Element Y should be inductive with X L = 20 
When X and Y are connector in series
