Figure 1
2. Experiment
1. Build the circuit in Figure 1 using TinkerCad, by interconnecting the appropriate resistors to a power supply (Voltage Source). Insert your name as an annotation. (25 points)
2. Measure the current and voltage for RL (10 points)
| Measured | |
| VRL (V) | |
| IRL (A) |
Table 1
3. RTH Measurement: (7.5 points)
Remove the source and replace it by a short circuit. Measure the RTH from the terminal a-b (without RL). record your measurement
| Measured | |
| RTH |
Table 2
4. VTH Measurement: (7.5 points)
1. Keep the source, measure the voltage across the terminal a-b (without RL). Record the value below:
| Measured | |
| VTH |

3. Analysis: (15 points)
1. Compare the results in tables 2 and 4. What are your observations?
2. In order to achieve Maximum power transfer to the Load which should be the value for RL?
3. What is the maximum power value at this RL?
4. Bonus:
Describe two practical applications of the maximum power transfer theorem: (5 points)
