Hello guys i am studying electronics for half an year and i need help with the superposition theorem. I have been headbanging for about 2 days now and i cant get up with an adequate answer corresponding to what MultiSim (software) had shown me as a value. Can any of you please give me an explanation about that particular one. I have been reading about it but never saw anything close to my example.. :/ any help will be appreciated! What i get as a results: Total resistance 1955Ohm corresponding to both sources. Its1 = 0.001023 A Its2 =0.001534 A. please dont let those numbers fool you, those are my calculations and at this point i am a bit unsure in myself. Best regards from one new forum member!

try eliminate dat 3v,replace it with a short, which means will be left with one power source (2v) and then find total resistance of the cct,find current flowing thru each resistor.
repeat the procedure using 3v battery alone.
FINALY SUM UP THE CURRENTS TOWARDS R4
hop this gona work

Superposition is one of the most important theorems in electrical engineering. I use it somewhat regularly in my engineering (maybe 2 to 3 times a month). It is very important that you understand this concept. I put superposition up there with ohms law, Norton and Thevenin equivalents, etc.
