Hey guys, I am supposed to solve for voltage and current on R4 using Thevenin's theorem here. Values are following: U = 100V R1 = 310 R2 = 610 R3 = 220 R4 = 570 R5 = 200 Now, I know I need to solve for Rth and Vth, so I put the circuit into simulation and figured out voltage on R3 is equal to voltage on R4, therefore that's my Vth. Although the theorem for current on R4 is IR4 = Vth / (Rth + R4) The simulation also showed current on R4 as 0.03 and pretty much my Rth would need to be as low as 12 to be suitable for this equation, which isn't possible given the current values for all resistors. Can anyone point me to the right direction? Thanks.
