Norton's theorem states that a complex network connected to a load can be replaced with an equivalent impedance

1. in series with a current source
2. in parallel with a voltage source
3. in series with a voltage source
4. in parallel with a current source

Correct answer: in parallel with a current source

Solution

Norton's theorem allows us to simplify a network by representing it as a current source in parallel with an equivalent impedance, which makes it easier to analyze the circuit's behavior when connected to a load.
