How does an inductor store energy?

An Inductor stores magnetic energy in the form of a magnetic field. It converts electrical energy into magnetic energy which is stored within its magnetic field. It is composed of a wire that is coiled around a core and when current flows through the wire, a magnetic field is generated. This article shall take a deeper look at the theory of how ...

Energy Stored on a Capacitor

The energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor. The voltage V is proportional to the amount of charge which is ...

Parasitic Inductance | Fundamentals | Capacitor Guide

Parasitic inductance. Parasitic inductance is an unwanted inductance effect that is unavoidably present in all real electronic devices. As opposed to deliberate inductance, which is introduced into the circuit by the use of an inductor, parasitic inductance is almost always an undesired effect. There are few applications in which parasitic ...
