For questions about Norton's Theorem, which states that a linear network of impedances, voltage sources, and current sources can be replaced with an equivalent network composed of a current source in parallel with an impedance. Consider also using the "thevenin" tag for questions also involving its dual, Thévenin's theorem.

Consider also using thevenin tag for questions also involving its dual, Thévenin's theorem, which uses a voltage source in series with an impedance instead of a current source in parallel with an impedance.
