The plates of a battery are insulated from each other, just like the plates of a capacitor. The purpose of the insulator is to create space between the plates where a static electric field may form. Here is a clearer and more complete explanation of what happens in a capacitor: allaboutcircuits.com/vol_1/chpt_13/1.html | |

I have a question: Why does current flow across the static electric field when it discharges ("when the capacitor discharges, it releases its potential in the form of current flowing across the static electric field")? I thought current can't flow across the plates of a capacitor because they are insulated from each other? | |
