Develop your own experiment that demonstrates numerically how capacitance changes with a dielectric, using values from the simulation. Use a standard process of science:

a. What is the hypothesis you want to explore?

b. How will you use the simulation to explore this hypothesis? (What is your procedure?)

c. What data did you collect as you ran the simulation?

d. Analyzing that data, was your hypothesis supported or rendered invalid?

e. What uncertainties do you expect to have in your data and results in an actual experiment?

For example, you might say that you want to explore how the insertion of a dielectric between the plates changes the E field. Your hypothesis might be that the E field would decrease, and that C increases. You set up the experiment to show the E field and record the plate separation d and Voltage differences of the top and bottom plate (so you can calculate the E field numerically from V = Ed).

You set up the experiment to show the E field and record the plate separation d and Voltage differences of the top and bottom plate (so you can calculate the E field numerically from V = Ed). You may run the experiment with a variety of voltages, record the results, and verify that the relationship of C = EA/d holds where s/co = K . Use different dielectrics think about graphing your data and getting information from the slope
