Question

This problem will ask you to find the Norton equivalent circuit at the terminals A-B.

For help, let us define all variables and write them in the circuit (we chose arbitrary directions and polarities):

You must realize by now (after doing all the previous problems in this set) that there are many ways to find the equivalent Thevenin and Norton circuits; here we only ask for the Norton. If you want to find IN first, you should consider v=0 in the circuit above. Or you could find RN, find VTh, then deduce IN. It is your choice!

Find the equivalent Norton circuit at terminals A-B:

a) iN = ?

b)  RN = ?

Explanation / Answer

a)iN = 1/2 *700 = 350 milli amperes b)Rn = R1 +R2 = 200 ohms
