Question

“Any two-terminal active circuit containing voltage sources and resistances, when viewed from its output terminals, is equivalent to a constant current source and an internal resistance.” This represents:

• A. Maximum power transfer theorem
• B. Superposition theorem
• C. Norton’s theorem
• D. Thevenin’s theorem

Hint:

Norton’s equivalent: current source + parallel resistance. Thevenin’s equivalent: voltage source + series resistance.

Answer 1

The Correct Option is C

Norton's theorem states that any two-terminal linear network can be replaced by an equivalent circuit consisting of a current source in parallel with a resistor. This is particularly useful for simplifying complex networks.
