The magnitude and direction of the current in the circuit shown will be

Options

A. `(7//3)` A from A to D via F
B. `(7//3)` A from D to A via F
C. `1.0 A` from A to D via F
D. `1.0 A` from D to A via F

Answer

c

Explanation

Total resistance of the circuit is
`R = 1+2 xx 3 = 6 Omega`
Effective emf of current `= 10- 4= 6V`
Current `I = ("effectively emf")/("total resistance") = (6)/(6) = 1A`
The direction of current would be from `A` to `D` via `F`
