Voltage Divider and Reducing Phase Angle Data Sheet
Problem 1 (Voltage Divider)
1. In the video, we showed that we required 𝑅1 = 2.33𝑅2 to get a 𝑉𝑂𝑢𝑡 = 3 𝑉𝑜𝑙𝑡𝑠. Derive a similar expression that will produce 𝑉𝑂𝑢𝑡 = 4 𝑉𝑜𝑙𝑡𝑠.
2. Based on part 1 and the requirement that 𝑅𝐿 ≥ 10𝑅2, select a value for R2 and Calculate R1:
R1=__________________ R2=________________
3. Measured VOut using the minimum load resistor (20 kΩ): ______________
4. Measured VOut using the maximum load resistor (100 kΩ): ______________
5. Does your voltage divider meet the specification?: ____________________
Problem 2 (Reducing Phase Angle)
6. Calculated inductive impedance, (𝑗𝜔𝐿) _____ _____ ____
7. Calculated Capacitance required to offset inductive impedance. __________
