if you look at the second circuit i have labeled the two nodes V_A and V_AB, those are the two nodes in which i am going to do nodal analysis in.doodle said:Before you can actually start solving the problem, you will need to identify firstly the two points A and B for which the Thevenin equivalent circuit is defined. So where are these points upon which you want to find the Thevenin equivalent circuit? Across the 10k resistor?
GREAT! thanks teknodude!teknodude said:I didn't calculate the Vth, but your work nodal analysis looks correct to me. On a side note, you didn't really need to convert the mA to A or the kohms to ohms. The prefixes will cancel giving you V during the calculations. Now find Rth to complete the problem.

doodle said:I have a few concerns.
1. Why remove the 10k resistor? Shouldn't the load resistor (if there should be one) be lying between the two points where the Thevenin equivalent circuit is defined?
2. I don't think [tex]V_{AB} = V_{Th}[/tex] as you have written in the solution. If the Thevenin equivalent circuit is to be determined across nodes AB and A, then [tex]V_{Th} = V_{AB} - V_A[/tex].
Thevenin Equivalent is a method used to simplify complex electrical circuits into a single equivalent circuit for analysis. It is named after French physicist Leon Charles Thevenin.
Thevenin Equivalent is calculated by finding the equivalent resistance of the circuit, which is the ratio of the voltage difference to the current flowing through the circuit. The equivalent voltage is then determined by measuring the voltage at the load terminals with the load disconnected.
Thevenin Equivalent is important because it allows for easy analysis and understanding of complex circuits. It also helps in designing and troubleshooting circuits, as well as predicting the behavior of a circuit under different load conditions.
Thevenin Equivalent is only applicable to linear circuits, meaning that the relationship between voltage and current remains constant. It also assumes that there are no independent sources in the circuit and that the load is purely resistive.
Thevenin Equivalent is commonly used in circuit design, power system analysis, and electronic device testing. It is also used in telecommunications, where it allows for the transmission of complex signals over long distances by simplifying the circuit.
