The magnitude and direction of the current in the following circuit is:- (a) 0.5 A from A to B through E (b) 5/9 A from A to B through E (c) 1.5 A from B to A through E (d) 0.2 A from B to A through E

Answer: (a). The two cells oppose each other: net emf = 10 - 5 = 5 V. Total resistance = 2 + 1 + 7 = 10 Ω. I = 5/10 = 0.5 A, in the direction set by the larger 10 V cell: from A to B through E. So the answer is (a).

The magnitude and direction of the current in the following circuit is :-

Show answer and solution

Answer: (a)

The two cells oppose each other: net emf $= 10 - 5 = 5$ V.
Total resistance $= 2 + 1 + 7 = 10\ \Omega$ .
$I = \frac{5}{10} = 0.5$ A, in the direction set by the larger $10$ V cell: from A to B through E.
So the answer is (a).
