This video explains how capacitors work and why they are essential in modern electronics. Capacitors store and release ...

Capacitors behave differently than resistors, where resistors allow a flow of electrons through them directly proportional to the voltage drop, and capacitors oppose changes in voltage by drawing or ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

You can make all sorts of different types of inductors, but the most common type is cylindrical coil of wire---a solenoid. When current runs through the first loop, it creates a magnetic field that ...

This Idea For Design shows how a gyrator circuit can be used to perform certain ac tests on units under test that require a dc-current feed. Designers have long used the gyrator circuit to create a ...

This video explains what capacitors are and how they store and release electrical energy in electronic circuits. Capacitors ...
