Norton’s current is equal to the current passing through the ___________ circuited ___________ terminals. a short, input b short, output c open, output d open, input 5 How can you found Norton resistance in the given circuit? a Shorting all voltage sources b Opening all current sources c Shorting all voltage sources and opening all current sources d Opening all voltage sources and shorting all current sources 6 Norton’s theorem is true for __________ a Linear networks b Non-Linear networks c Both linear networks and nonlinear networks d Neither linear networks nor non-linear networks Explanation 1 After removed the load resistance, acsoss the two nodes of it, we measure the open-circuit voltage. 2 This is the correct answer only. 3 This is the correct answer only. 4 Explanation: Norton’s current is equal to the current passing through short circuited output terminals not the current through open circuited output terminals. 5 Explanation: Ideal current sources have infinite internal resistance hence behave like an open circuit whereas ideal voltage sources have zero internal resistances hence behave as a short circuit. So, to obtain Norton resistance, all voltage sources are shorted and all current sources are opened. 6 Explanation: Norton’s theorem works for only linear circuit elements and not non-linear ones such as BJT, semiconductors etc.
