Nthevenin's theorem proof pdf

Proof of thevenin and norton theorem physics stack exchange. Thevenins theorem proof thevenin s theorem says a complicated network of resistors and sources, when viewed from a port, can be simplified down to one voltage source and one resistor. So the two terminals of the circuit can be modelled as a constant resistance in series with the open circuit voltage to get thevenins theorem. The circuit is linear, which means that any differential change in current or voltage depends on the circuit elements alone, and not on the currents and voltages. Thevenin theorem definition according to the thevenin s theorem, any linear bilateral network irrespective of its complexities can be reduced into a thevenin s equivalent circuit having the thevenins open circuit voltage vth in series with the thevenin equivalent resistance rth along with load resistance rl. Proofs and mathematical reasoning university of birmingham. This chart does not include uniqueness proofs and proof by induction, which are explained in 3. This video deals with the proof of thevenins theo rem in a simple way possible.

In fact, most such systems provide fully elaborated proof. The relationship f x between cause x and effect y is linear if f. Any linear electric network or complex circuit with current and voltage sources can be replaced by an equivalent circuit containing of a single independent voltage source vth and a series resistance rth. Thevenins theorem and its dual, nortons theorem, are widely used to make circuit analysis simpler and to study a circuits initialcondition and steadystate response. Calculate the output voltage, v, when in open circuit condition no load resistormeaning infinite resistance. Introduction to mathematical arguments math berkeley. The objective of this paper is to use a unique mathematical analysis of a purely resistive electrical circuit to prove the validity of thevenin s theorem by analysing the relationship between voltages and resistances in a simple electrical. Comparing mathematical provers institute for computing and. Calculate the output current, i ab, when the output terminals are short circuited load resistance is 0. Proof theory was created early in the 20th century by david hilbert to prove the consistency of the ordinary methods of reasoning used in mathematics. Thevenin theorem, thevenins theorem solution example. Nortons theorem maximum power transfer theorem supernode circuit analysis thevenin s theorem may be stated below. A more general statement of thevenin s theorem is that any linear active network consisting of independent or dependent voltage and current source and the network elements can be replaced by an equivalent circuit having a voltage source in series with a resistance, that voltage source being the open circuited voltage across the open circuited load.
