Question

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

 

विकल्प

• ${\displaystyle \frac{2}{3}}$ A from a to b through e.

• ${\displaystyle \frac{2}{3}}$ A from b to a through e.

• 3 A from b to a through e.

• ${\displaystyle \frac{10}{3}}$ A from a to b through e.

Answer 1

The magnitude and direction of the current in the circuit shown will be ${\displaystyle \underline{\frac{2}{3}\text{A from b to a through e}}}$.

Explanation:

Since, E₁(8 V) < E₂ (12 V), 

the current in the circuit will be anticlockwise.

Applying Kirchhoff's voltage law to loop aebcda

2I + 8 - 12 + I + 3I = 0

∴ I = ${\displaystyle \frac{2}{3}}$ A(b to a via e)
