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?
