Question

Norton's theorem

Answer 1

Problem

Answer 2

What's Norton's theorem

Answer 3

Norton's Theorem. Any collection of batteries and resistances with two terminals is electrically equivalent to an ideal current source i in parallel with a single resistor r. The value of r is the same as that in the Thevenin equivalent and the current i can be found by dividing the open circuit voltage by r.

Answer 4

I know the definition ^^, I am stuck with this problem particularly

in the solution manual it omits the 3 mA source when finding either short circuit current or open circuit voltage to find the Rth

Answer 5

@radar

Answer 6

To find the Norton's theorem you have to short circuit Independent voltage sources (replace voltage sources with wires) and Independent current sources have to be replaced by open circuit.
So for 3mA current source (independent) we open circuit it so we have to omit it. Open circuited elements have no influence in the circuit

Answer 8

I am stuck with this problem specially

The solution manual omits the 3 mA current source when finding either OC voltage or SC current.

Answer 9

but good paper by the way, got some nice notes.

also in the solution manual it assumes that the voltage accross a resistor remains the same weather it's open circuit or short circuit so it solves once for the voltage across a resistor assume v = 1.52 (not Voc) when solving for OC voltage

and use it in finding the the short circuit current
