Capacitor won't discharge

WebElectronics Hub - Tech Reviews Guides & How-to Latest Trends WebThe capacitor won't "concentrate" the energy from the battery / solar cells / any other energy source. Not much anyway, unless your power source is extremely weak and your load is super light. The energy stored in a capacitor is: \$ U = \frac {1} {2}CV^2 \$. Let's say you can charge that capacitor up to 5V.
