Mathematically, energy stored in an inductor is expressed as. Where w is the energy stored in the inductor, L is the inductance and i is the current passing through the inductor. Ideal inductors have a noteworthy characteristic - they do not dissipate energy. This trait allows the energy stored within them to be harnessed at a later point in time.

Inductors and capacitors both store energy, but in different ways and with different properties. The inductor uses a magnetic field to store energy. When current flows through an inductor, a magnetic field builds up around it, and energy is stored in this field. The energy is released when the magnetic field collapses, inducing a voltage in the ...

Capacitors and inductors are similar electrical components that impede the current in a circuit; unlike a resistor, they store the energy instead of dissipating it. A capacitor stores energy in an electric field, while an inductor stores energy in a magnetic field. Capacitors resist changes in voltage and current does not pass through them ...

Q is the charge in coulombs, V is the voltage in volts. From Equation 6.1.2.2 we can see that, for any given voltage, the greater the capacitance, the greater the amount of charge that can be stored. We can also see that, given a certain size capacitor, the greater the voltage, the greater the charge that is stored.
