Find the Norton current INo. Calculate the output current, IAB, with a short circuit as the load (meaning 0 resistance between A and B). This is INo.
so ino = i *15/(15+(15||15))*(15/(15+15)) = 0.12a
Find the Norton resistance RNo. When there are no dependent sources (all current and voltage sources are independent), there are two methods of determining the Norton impedance RNo :
Calculate the output voltage, VAB, when in open circuit condition (i.e., no load resistor – meaning infinite load resistance). RNo equals this VAB divided by INo.
vab = 0.6 * (15||(15+15))*15/(15+15) = 3v rno = vab/ino 3/0.12 = 25 ohm.
or
Replace independent voltage sources with short circuits and independent current sources with open circuits. The total resistance across the output port is the Norton impedance RNo.
rno = ((15+15)||15) +15 = 25 ohm.
This is equivalent to calculating the Thevenin resistance.
