Data Sheet Part 1 (15 points): Voltage Divider Design What do you think the purpose of the diode rectifier is in this design? Connect the load resistor (RL = 1k Ohms) to your solar panel and measure the voltage and current the solar panel can produce over different light conditions. (Reminder - voltage is measured with the multimeter in parallel with the resistor and current is measured with the multimeter in series with the resistor.) Solar Panel Voltage (V) Solar Panel Current (mA) Light Condition Full Sunlight Shaded Sunlight Lab Light Plus Phone Light Lab Light The CEO of Sparky Solar, Melanie Waters, has told you that the design criteria (in order of importance) are: 1. Availability, 2. Cost, 3. Accuracy. When designing the voltage divider circuit, which set of resistors will you use (1, 2, or 3) and why? Select R1 and R2 to ensure that the value of Al does not exceed 5V for all light conditions (show your work here and mention the maximum voltage your solar panel is capable of outputting): R1 (Ohms) R2 (Ohms) (Make sure it is in your stock) (Make sure it is in your stock) Max Voltage in to Pin A1 (V) 13
Which light condition should be considered when selecting R1 and R2 and why? If you replaced your solar panel with another one that is of a higher voltage, what is the maximum voltage that the solar panel can output without exceeding the power rating of your selected R1 and R2? Assume your resistors are 14 W resistors. (If your solar panel can exceed this voltage value, you will need to reselect your R1 and R2 values). Max voltage for R1: R2: Part 2 (15 points): Op-Amp Design Vsolar (V): Create a simulation of your Voltage Divider circuit in LTSPICE or TinkerCAD and attach an image of your schematic here (Choose one of the sunlight conditions you used above in your simulations. Mention which one you chose): Using your measurements/calculations of R1, R2 and the current supplied by the solar panel, calculate the maximum power dissipated by your load resistor (RL). Assuming your resistors to be 14 W resistors, will your resistors exceed this power rating? If so, you need to use a different resistor (with the same resistance but a higher power rating). Include your calculations here: Do your measured Voltage Divider results (V of R2) from your built circuit match your simulated results? How much error are you seeing? What are some possible reasons for the difference in the real and theoretical results? Choose one of the sunlight conditions you used above to compare your results. Mention which one you chose.
