The maximum amount of charge you can store on the sphere is what we mean by its capacitance. The voltage (V), charge (Q), and capacitance are related by a very simple equation: C = Q/V. So the more charge you can store at a given voltage, without causing the air to break down and spark, the higher the capacitance.

Transcript. Capacitors store energy as electrical potential. When charged, a capacitor''s energy is 1/2 Q times V, not Q times V, because charges drop through less voltage over time. The energy can also be expressed as 1/2 times capacitance times voltage squared. Remember, the voltage refers to the voltage across the capacitor, not necessarily ...

You actually convert this energy twice: first, you take the energy stored as charge at a potential (on the input) and store it in the magnetic field of the inductor. If voltage on a capacitor is potential energy, then the inductor is like a flywheel, and it stores the energy for a short duration as kinetic energy.

Strategy. We use Equation 9.1.4.2 to find the energy U1, U2, and U3 stored in capacitors 1, 2, and 3, respectively. The total energy is the sum of all these energies. Solution We identify C1 = 12.0μF and V1 = 4.0V, C2 = 2.0μF and V2 = 8.0V, C3 = 4.0μF and V3 = 8.0V. The energies stored in these capacitors are.

When capacitors are placed in parallel with one another the total capacitance is simply the sum of all capacitances. This is analogous to the way resistors add when in series. So, for example, if you had three capacitors of values 10µF, 1µF, and 0.1µF in parallel, the total capacitance would be 11.1µF (10+1+0.1).
