In this video we look at how centrifugal pumps work, it’s main components induction motor, shaft, bearings, impeller and pump casing. The video lecture explores and explains the working principles of a Centrifugal pump providing real life examples.
In this video, we learn how three phase electricity works from the basics. The basics of Three-phase electricity explained. We start with a simple single-phase AC generator and then add in a second and third phase to understand its working principle. We also cover three-phase power uses and distribution as well as why we don’t … Read more
Single phase electricity explained. In this video we learn electrical engineering basics by learning single phase meter wiring diagram. How electricity reaches our homes from the power station, transformer, transmission lines, distribution cables, service head and main fuse, electricity meter, main isolation switch, residual current device and circuit breaker. Electricity basics, how electricity works.
Star Delta Starters Explained. How do star-delta starters work for three-phase induction motors and why do we use star-delta starters. We cover the basics of how three-phase induction motors work. The basics of each star and delta configuration, a wiring diagram, animations of star delta starters and some simplified worked example calculations.
In 1961 two researchers, Robert Biard and Gary Pittman discovered that a certain compound was capable of emitting infrared radiation when passed through an electric current. This compound is GAAS (Gallium Arsenide), this compound is used in the manufacture of rectifier diodes and others. However, ultraviolet radiation cannot be seen with the naked eye, so in 1962, … Read more
Capacitors arose from the need to store electrical charges in order to use them flexibly in the future when there is resistance in their terminals. The capacitor is an electronic component capable of storing electrical charge when connected to a voltage source, the capacitor has two terminals for its polarization (the largest terminal is positive and … Read more
