Hi. It's me again. Right now I have some troubles with Thevenin's and Norton's theorem.
Here is the circuit.
I have to find the thevenin voltage Vth and thevenin resistance Rth and solve the circuit when there is a 2000Ω resistor connected to A and B.
Then, I try to solve it...
First, for the Rth, I just treat the voltage source as a short circuit and current source as an open circuit. So, the 4000Ω resistor is disconnected.
Rth = 2000Ω
Then, for the Vth, Vth = Voc.
By using KCL,
5/2000 + 0.1×10-3 = Voc/Rth
5/2000 + 0.1×10-3 = Voc/2000
∴ Voc = 5.2 V
i.e. Vth = 5.2 V
Is this correct?
