Chapter 28: Q. 53 (page 793)

What is the current in the $2 Ω$ resistor in FIGURE P28.53?

Short Answer

Expert verified

The current will be $3 A .$

Step by step solution

01

Given information

We have given,

resistances = $2 Ω, 4 Ω$

Voltage supply = $9 V, 3 V$

We have to find the current across $2 Ω$ .

02

Simplify

Using Kirchhoff voltage rule and let current flowing in the circuit is I.

$\sum_{i} V = 0 - 9 V + 3 V + 2 Ω \times I = 0 I = \frac{6}{2} I = 3 A$
