Question

What is the Thevenin equivalent of the circuit shown below?
a) Draw the Thevenin equivalent circuit and label the voltage and resistance.
b) What value of the load resistor will give maximum dissipation of power in
the load? 

The image shows a simple electrical circuit diagram. It consists of the following components:

1. **Voltage Source**: 
   - Labeled as 10 V, indicating it provides a 10-volt potential difference.
   
2. **Resistors**: 
   - Three resistors in the circuit.
   - The first resistor is labeled as 15 Ω (ohms).
   - The second resistor is labeled as 10 Ω.
   - The third resistor is labeled as 25 Ω.
   
3. **Load Resistor**:
   - Labeled as "Load Resistor," it is connected across the circuit in a parallel manner after the 25 Ω resistor.

**Circuit Configuration**:
- The voltage source is connected in series with the 10 Ω resistor, followed by the 25 Ω resistor.
- The 15 Ω resistor is connected in parallel with the series combination of the 10 Ω and 25 Ω resistors.
- The load resistor is connected at the end, in parallel with the existing setup.

This configuration allows for current division among the branches, with the voltage across parallel branches remaining consistent. The diagram is a clear representation of a mixed series-parallel circuit.
