Chapter 28: Q. 53 (page 793)

What is the current in the2鈩�resistor in FIGURE P28.53?

Short Answer

Expert verified

The current will be3A.

Step by step solution

01

Given information

We have given,

resistances = 2鈩�,4鈩�

Voltage supply = 9V,3V

We have to find the current across 2鈩�.

02

Simplify

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

鈭�iV=0-9V+3V+2鈩�脳I=0I=62I=3A
