Understanding inductance and the current can help control the energy storage capability of an inductor in different electronic and electrical applications. 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.
To define, the energy stored in an inductor is the energy induced in the magnetic field due to the flow of electric current. When a current flows through an inductor, it develops an electromagnetic field around it. This field is dynamic - meaning it changes with time and the amount of the current flowing.
These characteristics are linked to the equation of energy stored in an inductor, given by: W = 1 2 L I 2 where W is the initial energy stored, L is the inductance, and I is the current. Additionally, the presence of a magnetic core material can further enhance the energy-storage capacity of an 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. In summary, both the inductance of the inductor and the current flowing through the circuit greatly influence the energy stored in an inductor.
The main goal of this research was to improve the design of the inductor in order to achieve higher energy densities, specifically by utilising higher current densities in the winding, coupled with the ability to limit the temperature increase of the inductor through the usage of an effective cooling system.
The formula for energy stored in an inductor is W = (1/2) L I^2. In this formula, W represents the energy stored in the inductor (in joules), L is the inductance of the inductor (in henries), and I is the current flowing through the inductor (in amperes).
