Chapter 28: Q. 45 (page 792)

What is the equivalent resistance between points a and b in FIGURE P28.45?

Short Answer

Expert verified

The equivalent resistance will be5.5惟.

Step by step solution

01

Given information

We have given,

The complex linear circuit.

We have to find the equivalent resistance between points a and b.

02

Simplify

We have to use the rule to calculate the resistance in parallel and series combinations.

By given diagram we can see that some of the resistances are in parallel. then

1Req1=14鈩�+16鈩�112鈩�Req1=0.5鈩�

Now left are in series. then,

localid="1651058783263" Req=(0.2+2+3)鈩�Req=5.5鈩�
