An inductor is a passive electrical component that stores energy in a magnetic field when electric current flows through it. The property of an inductor that quantifies its ability to store this energy is known as inductance. Understanding the working principle of inductance is essential for engineers and technicians alike, as it influences the design and functionality of many electronic devices. This article will delve into the basic concepts of inductance, the working principles of inductors, their behavior in circuits, applications, and the factors affecting their performance.
II. Basic Concepts of Inductance
A. Definition of Inductance
Inductance is defined as the property of an electrical conductor that opposes a change in current. When the current flowing through an inductor changes, it induces a voltage in the opposite direction, according to Lenz's Law. This property is measured in henries (H), named after the American scientist Joseph Henry, who made significant contributions to the field of electromagnetism.
B. Historical Background
The concept of inductance emerged in the 19th century, primarily through the work of Michael Faraday and Joseph Henry. Faraday's experiments with electromagnetic induction laid the groundwork for understanding how changing magnetic fields can induce electric currents. Henry's work further explored the relationship between current and magnetic fields, leading to the formal definition of inductance.
C. Units of Inductance (Henry)
The henry is the SI unit of inductance. One henry is defined as the inductance of a circuit in which a change in current of one ampere per second induces a voltage of one volt. This unit provides a quantitative measure of an inductor's ability to store energy in a magnetic field.
D. Relationship Between Current and Magnetic Field
The relationship between current and magnetic field is fundamental to understanding inductance. When current flows through a conductor, it generates a magnetic field around it. The strength of this magnetic field is proportional to the amount of current flowing through the conductor. In an inductor, this magnetic field is concentrated and can store energy, which is released when the current changes.
III. The Working Principle of Inductors
A. Electromagnetic Induction
1. Faraday’s Law of Electromagnetic Induction
Faraday's Law states that a change in the magnetic field within a closed loop induces an electromotive force (EMF) in the loop. This principle is the foundation of how inductors operate. When the current through an inductor changes, the magnetic field around it also changes, inducing a voltage that opposes the change in current.
2. Lenz’s Law
Lenz's Law complements Faraday's Law by stating that the direction of the induced EMF will always oppose the change in current that created it. This opposition is what gives inductors their unique behavior in circuits, as they resist sudden changes in current.

\[ X_L = 2\pi f L \]
where:
- \( f \) = frequency of the AC signal
- \( L \) = inductance in henries
2. Frequency Dependence
Inductive reactance increases with frequency, meaning that inductors will oppose higher frequency signals more than lower frequency signals. This property is utilized in filtering applications.
B. Time Constant in RL Circuits
1. Charging and Discharging of Inductors
In an RL circuit (a circuit with a resistor and an inductor), the time it takes for the current to reach its maximum value when a voltage is applied is determined by the inductance and resistance. The inductor resists changes in current, leading to a gradual increase in current.
2. Time Constant Formula
The time constant (τ) for an RL circuit is given by:
\[ \tau = \frac{L}{R} \]
where:
- \( R \) = resistance in ohms
This time constant indicates how quickly the inductor responds to changes in current.
C. Energy Storage in Inductors
1. Magnetic Field Energy
Inductors store energy in the magnetic field created by the current flowing through them. This energy can be released back into the circuit when the current decreases.
2. Energy Storage Formula
The energy (W) stored in an inductor is given by the formula:
\[ W = \frac{1}{2} L I^2 \]
where:
- \( I \) = current through the inductor
This formula highlights the relationship between inductance, current, and energy storage.

III. Inductors in Parallel
A. Explanation of Parallel Circuits
In a parallel circuit, multiple components are connected across the same voltage source, allowing the current to split among them. Each component experiences the same voltage, but the current through each component can vary based on its resistance or inductance.
1. Characteristics of Parallel Connections
In parallel configurations, the total current flowing into the circuit is the sum of the currents through each inductor. This characteristic is crucial for understanding how inductors behave when connected in parallel.
2. Current Distribution in Parallel Inductors
The current through each inductor in a parallel configuration is inversely proportional to its inductance. This means that inductors with lower inductance will carry more current than those with higher inductance.
B. Mathematical Representation of Inductors in Parallel
1. Formula for Total Inductance in Parallel
The total inductance \( L_t \) of inductors connected in parallel can be calculated using the formula:
\[
\frac{1}{L_t} = \frac{1}{L_1} + \frac{1}{L_2} + \frac{1}{L_3} + \ldots + \frac{1}{L_n}
\]
Where \( L_1, L_2, L_3, \ldots, L_n \) are the inductances of the individual inductors.
2. Derivation of the Formula
The derivation of the total inductance formula involves considering the voltage across each inductor, which remains constant in a parallel configuration. By applying Kirchhoff's voltage law and the definition of inductance, we arrive at the formula for total inductance.
3. Example Calculations
For example, if we have two inductors with inductances of \( L_1 = 2 \, H \) and \( L_2 = 3 \, H \), the total inductance can be calculated as follows:
\[
\frac{1}{L_t} = \frac{1}{2} + \frac{1}{3} = \frac{3 + 2}{6} = \frac{5}{6}
