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)
Take a screenshot of your circuit and paste it here
2. Measure the current and voltage for RL (10 points)

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

4. VTH Measurement: (7.5 points)
1. Keep the source, measure the voltage across the terminal a-b (without RL). Record the value below:
