Widener University ENGR 111 – Projects Project 2– HW 1: Energy Conversion and Wind Turbine Design Fundamentals Due on Wed., November 9th (Submit Electronic Copies only) 1. Using Excel, graph the Ohm’s Law activity results from Table 1 in Instructions. Plot the following: - V1-2 vs. (I) and identify slope = R1 - I vs. R2, and I vs. R1-3 on the same graph 2. Develop an Excel spreadsheet, which can calculate theoretical frequency f of the oscillator resistances R1, R2, and capacitance C : (Equation 5) in the Instructions: 𝑓= 1.46 (𝑅1 +2𝑅2 )𝐶 3. Graph f = (R2) for R2 between 0 and 50 k and constant values of R1 and C, as in the Instructions 4. Calculate the two theoretical values of R2 needed to generate the assigned target frequencies for electronic notes (see Table 2 in the Instructions).
