Power Factor Improvement & Correction | Power Triangle & Capacitor Banks

The electrical energy is almost exclusively generated, transmitted and distributed in the form of alternating current. Therefore, the question of power factor immediately comes into picture. Most of the loads (e.g. induction motors, arc lamps) are inductive in nature and hence have low lagging power factor. Low power factor is highly undesirable as it causes… Read More: Power Factor Improvement & Correction | Power Triangle & Capacitor… »

Power Amplifier: Types, Classifications, and Applications

What is an amplifier? An amplifier is a device used to increase an input signal’s voltage, current, or power. A weak electrical signal is taken in and converted into a stronger output signal. External power is used to cause this change. There are three main classifications of amplifiers depending on the changes it makes to… Read More: Power Amplifier: Types, Classifications, and Applications »

Lead Acid Batteries: Functioning, Safety, and Maintenance

Lead acid batteries were the first form of rechargeable battery which are still used today. As we learned in history of batteries; lead acid batteries were developed in 1859 by Gaston Plante. This battery type is still used today in many industries, especially popular as car batteries, but also commonly used in photovoltaic systems. Compared… Read More: Lead Acid Batteries: Functioning, Safety, and Maintenance »

Difference Between Superconductor and Semiconductor

What is an electrical conductor? A material that permits the flow of electrical current is referred to as an electrical conductor. There are a variety of electrical conductors, but we will be focusing on two types which are semiconductors and superconductors. The key difference between a semiconductor and superconductor is that the conductivity of a… Read More: Difference Between Superconductor and Semiconductor »
