Solving Thevenin Equivalents: Techniques and Steps

In summary, the problem involves using circuit analysis techniques to determine the values of the Thévenin equivalent seen by a 20 kΩ resistor. The equivalent circuit will consist of an ideal voltage source and one resistor, but the method of reducing the circuit has not been taught. Attempting to reduce using series/parallel only simplifies the 10k and 8.2k resistors. Further assistance is requested.

The Attempt at a Solution



I know a Thévenin equivalent is an ideal voltage source and one resistor, but We haven't been taught how to reduce a circuit the appropriate way. I would try to reduce using series/parallel, but that only reduces the 10k and 8.2k resistors.

Any help would be much appreciated.

FAQ: Solving Thevenin Equivalents: Techniques and Steps

1. What is the Thevenin equivalent circuit?

The Thevenin equivalent circuit is a simplified representation of a complex electrical circuit that has a single voltage source and a single resistance connected to a load. It is used to analyze and solve circuits by reducing them into simpler circuits.

2. How is the Thevenin equivalent circuit calculated?

The Thevenin equivalent circuit is calculated by removing the load from the original circuit and determining the open-circuit voltage and the equivalent resistance. The open-circuit voltage is the voltage across the load terminals, and the equivalent resistance is the resistance seen from the load terminals.

3. What is the purpose of using Thevenin equivalent circuits?

The purpose of using Thevenin equivalent circuits is to simplify complex circuits and make them easier to analyze. It is also used to find the maximum power transfer to a load and to determine the behavior of a circuit under different load conditions.

4. Can Thevenin equivalent circuits be used for both AC and DC circuits?

Yes, Thevenin equivalent circuits can be used for both AC and DC circuits. The calculations are the same, but the values of voltage and resistance may differ for AC and DC circuits due to the effects of frequency and impedance.

5. How do I use Thevenin equivalent circuits in circuit analysis?

To use Thevenin equivalent circuits in circuit analysis, you need to first determine the Thevenin equivalent voltage and resistance for the circuit. Then, you can replace the original circuit with the Thevenin equivalent circuit and analyze it using standard circuit analysis techniques.
