Homework Equations
Req = R1R2 / R1+ R2
P = V^2 / R
Thanks you for your time.
The Attempt at a Solution
I am not understanding what they meant by "seem by the source"
so I assume that they want to find R equivalent for the whole thing.
Start from the right to left
2Ω + 1Ω = Req1 = 3Ω
Req1 || 3Ω = Req2 = 1.5Ω
4Ω + 1.5Ω+5Ω || 6Ω = Req3 = 3.82Ω
---->ReqS = 3.82Ω + 7Ω = 10.82Ω
---->Ps = Vs2/ ReqS = 18.11 W
