Launch the simulation by pressing the triangle

(') 1. Launch the simulation by pressing the triangle. Note this simulation may not run on Ipads. Take a few minutes to familiarize your self with the simulation. When you are done exploring, please press "reset all" before answering the questions.

(')) 2. Using the default values for the plate area and the distance between the plates, calculate the capacitance of the

capacitor in the picture.

3. Imagine that you have a capacitor with round plates, instead of the square plates shown in the simulation. In your capacitor with round plates, the separation between the plates is four times larger than the separation between the plates of the capacitor in the simulation. Calculate the radius of one of the round plates, if your capacitor has the capacitance you calculated above.

' Hint: What's your area equation now?
