The former is applied by using a voltage source while the latter uses a current source. Thevenin It is a theorem related to linear electrical systems. It states that any number of resistors, current and voltage sources can be decreased up to an equal amount of voltage sources and a resistor that is attached with the voltage supply.
It was first discovered in by a German scientist, Hermann von Helmholtz. It was then rediscovered by Leon Charles Thevenin who was a French telegraph engineer back in Then the result is used to model and simulate how the circuit will behave when different components are used to close the circuit path. This theorem is very useful because of the conversion of real life components to ideal components.
The properties of these ideal components are relatively easy to calculate. This theorem can also be used to alternative current circuits by applying impedance instead of resistance.
This theorem is also very useful when it comes to circuit simulations. What is the difference between Thevenin and Norton theorems? V Th , can be calculated from voltage division.
Thevenin equivalent circuit will be Maximum power transfer. Hence, the power will be. To find Vth and Rth First, we assume that the load resistor is infinite. Open circuit Calculate Vth in original circuit using open circuit condition Second, reduce the load resistance to zero short circuit.
Condition, if more short circuit access the terminal and in general circuit. Take the voltage sources out, make a short circuit Take the current sources out, make an open circuit Then calculate from the circuit.
