Expert Solution
Step 1
In the given circuit we can see resistance 15.5Ω and 4.50Ω are in parallel between point a and b. Therefore their net resistance will be
 (12).gif)
And we can see resistance 20.0Ω and 4.50Ω are in series. Therefore their net resistance will be R'=4.50+20.0=24.5Ω
Therefore the new circuit diagram is
