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
Answer: Option B
:
B
If resistance is constant (10Ω) then steady current in the circuit i=510=0.5A . 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.
