An ideal choke takes a current of 8 A when connected to an a.c. source of 100 volt and 50 Hz. A pure resistor under the same conditions takes a current of 10 A. If two are connected in series to an a.c. supply of 100 V and 40 Hz , then the current in the series combination of above resistor and inductor is
A
10 A
B
8 A
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
So, impedance of the series RC circuit at a frequency of 40 Hz is
Hence current in the 
circuit now
