Output resistance problem 1. The problem statement, all variables and given/known data Hi, I am not getting the answers right, and I think I misunderstand the logic behind this circuit. http://imageshack.us/photo/my-images/577/screenshotfvm.png/ 2. Relevant equations I know that the equation of Vin is Vin=(VsRin)/(Rs+Rin) and the equation of Vout is Vout=(GVinRl)/(Rout+Rl) 3. The attempt at a solution I have found Vin right just from the equation to be equal to 5V. But when I had to calculate the Vout I found to be 25V instead of 50V(given answer) Also on the other question where I have to find the output resistance, I think it will be 200ohms, but it is given to be 100Ohms. The logic I found here is the 2 final resistors to be calculated as Parallel and then I get the answer of 100Ohms. Also the final question where is said that if we remove the Rl the what should be the output resistance. And I think it will be 100 because of the Rout is 100Ohms but Again when the previous part is not correct with my logic I expect here to misunderstand something. Thanks very much!
