A) 0.4 A
B) 0.3 A
C) 0. 2 A
D) 0.1 A
Correct Answer: D
Solution :
From the figure, we see that emfs are in opposite directions Hence, the resultant emf is given by \[=5-2=3V\] and external resistance in the circuit is = 10 + 20 = 30 Hence, the current in the circuit is given by \[i=\frac{V}{R}=\frac{3}{30}=0.1\,\text{amp}\]
