Question

In the circuit shown, the magnitude and direction of the flow of current is

• A. 0.8 ampere from A to C via B
• B. 0.8 ampere from C to A via B
• C. 0.5 ampere from A to C via B
• D. 0.5 ampere from C to A via B

Answer 1

Answer: (C)

0.5 ampere from A to C via B

Answer 2

Net $e.m.f$= 8 - 2 = 6 V
Effective resistance = 1 + 2 + 9 = 12 $\Omega$
{since} current, I = $\frac{6}{12} = 0.5$ A form A to C via B.
