As Lenz’s Law states, an inductor in a circuit opposes the flow of current through it because the flow induces an electromotive force (emf) that opposes it. In order to keep the current flowing ...

Inductive Reactance is defined as the opposition to current flow. It is the reaction of the inductor to the changing value of alternating current. To explain further, a back electromotive force (emf) ...

Not mean to be tried at home! When we cut the electricity to an inductor, we get a sudden intense spark across the switch. This is known as inductive kickback or a back EMF and is produced because of ...

A typical Twin Feeder cable, or more popularly referred to as "Zip Cord", consists of two adjacent conductors separated by insulation, or commonly referred to a "dielectric". For convention we assume ...

Last month, we clarified the definition of a vector and showed you how vectors are added, subtracted, multiplied, and divided. This month, we'll see how to use vectors in defining a complex circuit ...

NCERT Solutions for Class 12 Physics, Chapter 6 - Electromagnetic Induction are available here. Some important topics of this chapter are Faraday and Henry experiments, magnetic flux, Faraday’s law of ...

Could the inductor be redesigned in a fundamentally new way? Yes, according to new work by researchers in the US, Japan and China who have made the first high-performance inductors from intercalated ...
