In the circuit diagram shown in figure given below, the current flowing through resistance $3Ω$ is $\frac{x}{3} A$ . The value of $x$ is ________.

Answer:

1.00

Solution:

Let the current flowing through the circuit be $I A$ in anti-clockwise direction.

The net resistance is $R = 4.5Ω + 2Ω + 1.5Ω = 8Ω$

Hence, $I = \frac{V}{R} = \frac{4 V}{8Ω} = 0.5 A$

The current flowing through the $3Ω$ resistor is

$\frac{6}{6 + 3} \times 0.5 = \frac{1}{3} A$

So, $x = 1$
