Frequently asked questions
- Can a capacitor store as much energy as a battery?
- Generally no. A typical 1 F supercapacitor at 2.7 V stores ~3.6 J, while a single AA alkaline battery stores ~15,000 J. Capacitors excel at releasing energy quickly (high peak power), not storing large amounts.
- Why does energy scale with V²?
- Each additional unit of charge added to a capacitor must be pushed against an increasing voltage, so the energy per coulomb increases linearly. Integrating Q × dV from 0 to V gives ½CV².
