Yes, it is possible to find the Thevenin equivalent by working stepwise though a circuit.

Note that the problem statement says to view the diode as the load, so for the purposes of finding the Thevenin equivalent you need to imagine that the diode is removed and the Thevenin equivalent is as viewed looking into the open terminals where the diode was.

First find Rth. Start by removing the load, in this case the diode, as gneil said, then turn off the voltage source by replacing it With a Short circuit

## 1. What is Thevenin Equivalent Circuit?

Thevenin Equivalent Circuit is a simplified representation of a complex circuit, which can be used to calculate the voltage and current characteristics of a circuit.

## 2. How is Thevenin Equivalent Circuit calculated?

Thevenin Equivalent Circuit is calculated by finding the equivalent resistance of the circuit by removing all voltage sources and shorting all current sources. The equivalent voltage is then found by connecting a load resistor and finding the voltage across it.

## 3. What is the purpose of finding Thevenin Equivalent Circuit?

The purpose of finding Thevenin Equivalent Circuit is to simplify a complex circuit into a single voltage source and a single resistor. This makes it easier to analyze and calculate the voltage and current values of the circuit.

## 4. How do diodes affect Thevenin Equivalent Circuit?

Diodes can affect Thevenin Equivalent Circuit by introducing non-linear characteristics to the circuit. This means that the equivalent voltage and resistance may vary depending on the applied load, making the calculations more complex.

## 5. Can Thevenin Equivalent Circuit be used for circuits with multiple power sources?

Yes, Thevenin Equivalent Circuit can be used for circuits with multiple power sources. The equivalent voltage and resistance can be calculated for each individual power source and then combined to find the overall equivalent voltage and resistance of the circuit.
