Hi hussain bani. You short the batteries only on paper. You don't do this to real batteries, shorting them can be dangerous or damaging, and won't give you the right answer, anyway, because the chemical reaction inside changes drastically when a battery is abused like this.hussain bani said:I short the batteries for Rth, but after doing short i don't understand how to find Rth, can someone help me finding out ?
In general, no. That won't work where the circuit includes active or non-linear devices (e.g., semiconductors).smashbrohamme said:In a circuit with other components, you can just take the batteries out and put a jumper wire where the batteries were.
A Thevenin equivalent circuit is a simplified representation of a complex circuit that contains a single voltage source and a single resistor. It is used to analyze and solve circuits by reducing them into simpler components.
To find the Thevenin resistance, you can remove all voltage and current sources from the original circuit and calculate the resistance between the two terminals where the load will be connected. This value will be the Rth of the Thevenin equivalent circuit.
The Thevenin theorem states that any linear circuit with voltage and current sources and resistors can be replaced by a single voltage source and a single resistor connected in series. This simplified circuit will produce the same voltage and current at the load as the original circuit.
Thevenin equivalent circuits allow for easier and quicker analysis of complex circuits. By reducing a circuit to a single voltage source and resistor, calculations become simpler and more manageable.
Thevenin equivalent circuits are only applicable to linear circuits, meaning that they do not apply to circuits with non-linear components such as diodes or transistors. Additionally, the Thevenin equivalent may only be accurate within a certain range of operating conditions.
