Questions
The resistance in the following circuit is increased at a particular instant. At this instant the value of resistance is . The current in the circuit will be now
detailed solution
Correct option is B
If resistance is constant (10 Ω), then steady current in the circuit i=510=0.5 A But resistance is increasing it means current through the circuit start decreasing. Hence, inductance comes in picture which induces a current in the circuit in the same direction of main current. So i>0.5 A.Talk to our academic expert!
