| What happens if we connect plates with a conducting wire? Excess electrons travel to positive plate - happens quickly at first b/c lots of repelling and strong attraction, happens more slowly as time goes on. Exponential decay of excess charge. (Corresponds to decay of electric potential.) Equilibrium definition. | What happens if we connect plates with a conducting wire?
