Thevenin's and Norton's theorems

  1. Aug 18, 2012 #1
    Please help. In Norton's circuit we have Isc(current), Rsc(Norton's resistance) and R load which the load resistance. I thought to find the voltage Voc I need to find the equivalent resistance of the two resistors and use ohms law to find Voc =Isc*Req. Is that right?

    No. R is the load. So in open circuit the load will not be present. Voc will be just Isc*Rsc (where Rsc is Thevenin or Norton resistance).
