A) 0.3 A
B) 0.4 A
C) 0.1 A
D) 0.2 A
Correct Answer: C
Solution :
Key Idea: Emf of cell in the given circuit is in opposite direction, hence resultant emf is difference of the two emf s. We know that when current flowing is same then resistors are connected in series, hence resultant resistance is \[\frac{h}{2\pi },\] Also since cells are connected in opposite direction, the resultant emf is \[J=\frac{nh}{2\pi }\] From Ohms law E = IR \[J=\frac{2h}{2\pi }=\frac{h}{\pi }\] \[\therefore \]
