Question

In the circuit diagram shown in the figure, the magnitude and direction of the flow of current, respectively would be

• A. $\frac{7}{3}A$ from $a$ to $e$
• B. $\frac{7}{3}A$ from $b$ to $e$
• C. $1A$ from $b$ to $e$
• D. $1A$ from $e$ to $b$

Answer 1

The correct option is C $1A$ from $b$ to $e$

As 10 V is greater, the current direction will be from the positive terminal of 10 V to the positive terminal of 4V.
So the current direction is $a\to d\to c\to b\to e\to a$

The current in the circuit $=\frac{\text{effective voltage}}{\text{effective resistance}}$$=\frac{6V}{6\Omega }$$=1A$

So the answer is $1A$ from $b$ to $e$.
