## Homework Statement

Find The Thevenins Equivalent of the circuit shown .

at the terminal a and b i think

## Homework Equations

Vth = Rth(Ith)

V= IR

## The Attempt at a Solution

For Vth

i tried using Nodal Analysis Having 4 Node Voltages

but i don't know if the 5 ohms resistor and 8 ohms resistor is having flow of current in there?

For Rth

the Current source is change into open ckt.

then solve by having 40 and 20 in series then parallel in 10 ohms

therefor [(40+20)x10]/70 + 45 + 5 + 8 = 78 ohms = RthSo I am wondering how should i get the Vth now,,

And is Vth = Va + 35V and Vth = Vb +15 V ? or I = (Va + 35 - Vth) / 5 ohms
