Chapter 28: Q. 52 (page 792)

The ammeter in FIGURE P28.52 reads3.0A. Find I1,I2,and 蔚.

Short Answer

Expert verified

The value of

I1=5AI2=8A蔚=14V.

Step by step solution

01

Given information

We have given,

Ammeter reading = 3A

We have to find the value ofI1,I2,蔚.

02

Simplify

Using the Kirchhoff voltage law in the upper loop

-9V+3鈩�脳I1=2鈩�脳3AI1=9+63I1=5A

Using Kirchhoff current rule at the node and substitute the value ofI1.

localid="1649416745087" I2=I1+3AI2=5A+3A=8A

Using Kirchhoff voltage rule in the lower loop

localid="1649416765380" (2鈩�脳3A)-蔚+(1鈩�脳I2)=0蔚=6+8蔚=14V
