The concept of the Capacitor Quality Factor and the associated formula have shaped the field of electronics and telecommunications in numerous ways. High-Q capacitors are desired in many applications, including filters, oscillators, and resonant circuits, where they minimize power loss and allow circuits to perform more efficiently.
Learn MoreThis formula demonstrates that the charge on a capacitor is directly proportional to both the capacitance and the voltage. A higher voltage or capacitance results in a greater charge stored on the capacitor. The above formulas are used in our Capacitor Energy Calculator, the use of which makes any calculation a matter of seconds.
