Introduction
Inductance can be a elementary concept in electrical engineering and physics, influencing how circuits behave underneath different electrical conditions. Whether or not you are working with a simple solenoid or intricate coaxial cables, being familiar with inductance is essential for creating productive electrical techniques. In the following paragraphs, we’ll dive into several sorts of inductance, such as the inductance of a solenoid, inductance in series and parallel circuits, and the connection concerning inductance and capacitance.

What is Inductance?
Inductance is the property of the electrical element, normally a coil or solenoid, that resists alterations in electric current. When The existing flowing by way of a coil adjustments, it induces a voltage (or electromotive force) opposing that change. This phenomenon is essential in the design of inductors, transformers, and various electrical circuits.
