Inductance of the coil: The amount of energy stored in an inductor is directly proportional to its inductance. Higher the inductance, higher will be the energy stored. Current flowing through the coil: The energy stored is directly proportional to the square of the current flowing through the inductor.
Energy in the inductor is stored in the form of a magnetic field. When current is applied, the energy of the magnetic field expands and increases the energy stored in the inductor. The energy remains constant as long as the current is maintained. If the current is removed, the energy is discharged as the magnetic field contracts.
Instead, the energy is stored in the magnetic field as the rising current forces the magnetic lines of force to expand against their tendency to become as short as possible—somewhat as a rubber band stores energy when it is stretched. Figure 1 Determining the energy stored by an inductor
The inductance (\ ( L \)) of an inductor, a measure of its ability to store energy in a magnetic field, is a fundamental property that determines how much opposition the inductor presents to changes in current, thus affecting the induced voltage.
B. The initial energy stored in an inductor depends on the coil inductance, the current passing through the inductor, and the rate of change of this current. The presence of a magnetic core material can also increase the energy-storage capacity.
Resistance of the coil: The resistance of the coil, while not directly present in the formula, influences the current through the inductor. A high resistance coil will allow less current to flow, thus reducing the energy stored. Hence, resistance indirectly affects the energy stored in an inductor.
