An inductor is passive component that stores energy in the form of a magnetic field when an electric current passes through it. It’s constructed by wounding wire around a core made of magnetic or non-magnetic material. The primary characteristic of an inductor is its inductance (L), which is a measure of its ability to store energy in the magnetic field.

When current flows through the coil of an inductor, a magnetic field is generated around the coil. The magnetic field stores energy, and when the current through the inductor changes, the magnetic field collapses, releasing the stored energy back into the circuit. This property of an inductor makes it different from capacitors, which store energy in an electric field.

There are many reasons why inductors are used in a electronic circuit :

  • Filtering and Signal Processing
  • Energy Storage
  • Inductive Load Control
  • Magnetic Coupling & Transformers
  • Chokes and Inductive Reactors
  • Inductive Sensing and Detection
  • Resonant Circuits
  • Energy Conversion
  • Electromagnetic Interference (EMI) Suppression

To calculate the series inductance, input the number of inductors and their respective inductance values, and the calculator will provide you with the total inductance

Understanding Series Inductance:

Current:Similar to resistors in series, the current flowing through every inductor in a circuit is the same.

Total Inductance: When inductors are coupled in series, the circuit’s total inductance rises. 

Voltage: In a series circuit, the voltage across each inductor can change based on the overall current flowing through the circuit as well as the values of each individual inductance.

Connection: Clear the leads and/or terminals of each inductor before connecting the free leads to the other components of the circuit to link inductors in series. 

Mutual Induction: Mutual induction occurs when two inductors are connected in series, meaning that the magnetic fields of the two inductors influence one another. 

Properties: Similar to series resistors, series inductors have uniform current flow and total impedance addition as basic characteristics. 

Series inductance is employed in many circuits in real-world applications, including resonant circuits, transformers, and filters. Comprehending series inductance is essential for the design and analysis of these circuits because it enables engineers to anticipate the circuit’s behavior and maximize its efficiency.

In conclusion, series inductance is a basic idea in electrical engineering, and building and debugging complicated circuits requires an awareness of its characteristics.
