Homework Statement
Use the mesh-current method to find v0.
Find the power delivered by the dependent source.
Homework Equations
v1+v2+..vn=0
i=v/R
p=iv
The Attempt at a Solution
eq #1)-i1*10+i2*20=25V
eq #2) i2*20+i2*24+6iΔ=0
eq #3) iΔ*14=21
eq#3) iΔ=1.5A
eq#3 sub into eq#2) i2=0.204A
i2 sub into eq#1) -1.6A
Power delivered=
p=iv
p=0.204A*(6*1.5)V = 1.839 W
I posted the solution below. I don't understand how they got it. They added up resistances, and also said i1*20 in the first equation, but i2*20 in the second. Also, I'm not sure how to get the polarities when the + and i signs aren't given. For example, the 24Ω resistor.
