Question

Can anyone Explain Thevenin's Theorem.........

Answer 1

In circuit theory, Thévenin's theorem for linear electrical networks states that any combination of voltage sources, current sources and resistors with two terminals is electrically equivalent to a single voltage source V and a single series resistor R. For single frequency AC systems the theorem can also be applied to general impedances, not just resistors. The theorem was first discovered by German scientist Hermann von Helmholtz in 1853, but was then rediscovered in 1883 by French telegraph engineer Léon Charles Thévenin (1857–1926).

This theorem states that a circuit of voltage sources and resistors can be converted into a Thévenin equivalent, which is a simplification technique used in circuit analysis. The Thévenin equivalent can be used as a good model for a power supply or battery (with the resistor representing the internal impedance and the source representing the electromotive force). The circuit consists of an ideal voltage source in series with an ideal resistor.

Answer 2

couldnt make it any simpilar then this

Answer 3

thanks it's good it will help me

Answer 4

yw :)

Answer 5

Then the theorem tells you how to work out the Thévenin equivalent emf and resistance.

Rth is Req when all sources have been turned off.
Eth is voltage across terminals when no current is drawn form the circuit.
