Hi,(adsbygoogle = window.adsbygoogle || []).push({});

New member here!

Ok, this is a textbook question which I need help with as I am self teaching myself Linear Circuits. I have an exam in a week and I wanted to clear out some questions I had.

1. The problem statement, all variables and given/known data

textbook question: here

Find Vo using Thévenin’s theorem

2. Relevant equations

Mesh Analysis:

I1 = 8mA (8mA current source loop)

I2 = 2mA (2mA current source loop)

Loop I3 : -I1(3kΩ) - I2(6kΩ) + I3(15kΩ) = -12V (voltage source loop)

I3 = 36/15 = 12/5 mA

R_th = 18/5 kΩ + 2kΩ

3. The attempt at a solution

Since we want to find Voltage across the 1kΩ resistor using Thevenin's theorem, I removed the resistor from the circuit.

Now to find the voltage across the Open terminals I would have to simplify the circuit. Where I am stuck is how I can simplify the rest of the circuit so that I have Voltage and R_th.

The current sources are baffling me, I dont know how to simplify those.

I tried using Mesh analysis because i have 2 of the 3 currents but I dont know how to use those currents to find a voltage across the terminals.

Any help would be appreciated.

Thanks,
