MHT CET Physics question
An ideal choke takes a current of 10 ampere when connected to an A.C. supply of 125 volt and 50 hertz. A pure resistor under the same conditions take a current of 12.5 ampere. If the two are connected to an A.C. supply of volt and 40 hertz, then the current in a series combination of the above resistor and inductor is
