The formulae to calculate the energy stored in capacitor can be given by E=1/2CV2 . So in our case for a 5.5V 1F capacitor when charged fully the energy stored will be. E = (1/2)* 1 * 5.52 E= 15 Joules. Now, using this value we can calculate how long the capacitor can power things, say for example if we need 500mA at 5V for 10 seconds.
