2. From your results in Table 2 of your lab procedure

a. Plot your measured generator voltage as a function of resistance using a log base 10 scale on the x axis.

b. Plot calculated generator power as a function of resistance using a log base 10 scale on the x axis.

c. For the resistor that produced the maximum generator power, calculate the maximum overall efficiency for the conversion of chemical energy to electrical energy for your Stirling engine/generator setup.

d. Compare your result for question 2c. in this lab for the conversion efficiency of chemical to electrical energy to your result for question 2d. in Homework #3 for conversion efficiency of chemical to mechanical energy. Explain your result.
