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 V

Then, I try to solve it...

First, for the R

R

Then, for the V

By using KCL,

5/2000 + 0.1×10

5/2000 + 0.1×10

∴ V

i.e. V

Is this correct?

Here is the circuit.

I have to find the thevenin voltage V

_{th}and thevenin resistance R_{th}and solve the circuit when there is a 2000Ω resistor connected to A and B.Then, I try to solve it...

First, for the R

_{th}, I just treat the voltage source as a short circuit and current source as an open circuit. So, the 4000Ω resistor is disconnected.R

_{th}= 2000ΩThen, for the V

_{th}, V_{th}= V_{oc}.By using KCL,

5/2000 + 0.1×10

^{-3}= V_{oc}/R_{th}5/2000 + 0.1×10

^{-3}= V_{oc}/2000∴ V

_{oc}= 5.2 Vi.e. V

_{th}= 5.2 VIs this correct?
