Capacitor Problem 9.4.1


 

Start Capacitor 1 Start Capacitor 2 Start Capacitor 3 Start Capacitor 4

Description

Four simulations represent parallel plate capacitors. You can click-drag and observe the electric potential at that point.   Note: There is a 1-5% intrinsic error in the calculation of charge.

Question

For which capacitors would you expect the effect of fringing to be minimal, i.e. the capacitance is C=e0A/d? 

Answer

Capacitors 3 and 4.
