Question
The resistance in the following circuit is increased at a particular instant. At this instant the value of resistance is 10W. The current in the circuit will be now
- i = 0.5 A
- i > 0.5 A
- i < 0.5 A
- i = 0
The correct answer is: i > 0.5 A
If resistance is constant (10 
) then steady current in the circuit 
. 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
