I'm trying to become more familiar with capacitors and whether its feasible for for a project. I found that Farad = Current * time / Voltage. In this project, we're trying to have some LED bulbs (12V, 20W) lit up for some period of time (at least 1 hour). I figured F=1.6A * 3600s / 12V = 480 Farads, which I realize is ridiculously huge for a small light system. Is my concept math right?
