Sahay Sir > Question Answers > The coefficient of mutual inductance of the two coils is 0.5 H. If the current is increased from 2 to 3 A ln 0.01 sec. In one of them
An ideal choke takes a current of 8A when connected to an a.c. source of 100 volt and 50Hz. A pure resistor under the same conditions takes a current of 10A. If two are connected in series to an a.c. supply of 100V and 40Hz, then the current in the series combination of above resistor and inductor is
