How to calculate the Power Factor Correction
Let us consider an inductive load taking a lagging current I at a power factor cosΦ1. For us to improve the power factor of such a circuit, the solution is to connect equipment in parallel with the load which takes a leading reactive component and partly cancels the lagging reactive component of the load. Figure…

AC vs DC Power & Motors – Differences and Benefits
AC and DC power isn’t new and yet it has been two main types of power we are taking advantage of even in the modern age we live in. But did you ever understand the difference between AC and DC power, did you know how we use it, and what is the preferred power type…

Alternating Currents and Voltages
Alternating current generator Let’s consider a signal turn coil rotating freely at a constant angular velocity symmetrically between the poles of a magnet as illustrated below: The ends of the loop are terminated in slip rings. As the loop rotates, side A will have an emf induced first in one direction and then in the…
