If we measure the voltage at the terminals of a two-terminal network with two known (anddifferent) resistive loads attached, we can determine the Thévenin and Norton equivalentcircuits. When a 2.2-kΩ load is attached to a two-terminal circuit, the load voltage is 4.4 V. When the load is increased to 10 kΩ, the load voltage becomes 5 V. Find the Thévenin voltage and resistance for this circuit.

Thevenin Theorem

Any linear circuit, no matter how complex, maybe simplified to an equivalent circuit utilizing only a single voltage source and series resistance coupled to a load, according to Thevenin's Theorem. The superposition principle says that all foundational equations must be linear, and the notion of "linear" is still the same (i.e., there should not be any exponentials or roots). This is particularly the case when operating with passive elements like resistors, inductors, and capacitors. However, some components (particularly some gaseous and semiconductor devices like tunnel diode, Schottky diode, transistors like BJT, MOSFET) are nonlinear, meaning their current resistance fluctuates with voltage and current. As a result, circuits made up of these parts are known as nonlinear circuits.
