Homework Statement
Find the current that flows through the ##8 \Omega##
Homework Equations
Thévenin's theorem
The Attempt at a Solution
the theorem says that I can replace all the circuit to a power source and a resistor connected in series.
So first I need to connect all the power sources, Can I choose it to be ##20V-8V+4V=16V##?
Secondly I need to fist the equivalent resistor, so first I will calculate the parallel ##4\Omega## and ##2\Omega## resulting a ##R_1=1.33\Omega## than to calculate ##R_1## with ##2\Omega## which are connected in parallel, resulting ##R_3=0.8\Omega## and now to connect all the others in series ##R_{Total}=0.8+4+4=8.8\Omega##
So ##I=\frac{16}{8.8}=1.81A## is it right?
