Circuit Breaker

Can you imagine a world where there is no control of the electric supply? As mentioned, electric power is the most dangerous form of energy in the world. So it is clear that if not controlled, results in the destruction of many thing, example human life, animal life, equipments, etc.   So to control the electric power, we developed these equipments such ass isolators ans circuit breakers. Automated control of electric power with pre-set values are done by Circuit Breakers[CB]. It was in 1879, the idea for a circuit breaker was developed by Thomas Alva Edison. A circuit breaker disconnect an electric circuit by simply opening a contact, when the monitoring system gives the trip signal. Now-a-days this monitoring systems are known as relay. Household circuit breakers are inbuilt with this mechanism. The circuit breaker is an absolutely essential device in the modern world, and one of the most important safety mechanisms in your home as well as in...

Hey there! Production of Electric energy Basic of generation of electric energy is a change in magnetic field and a coil placed near it connected to the load. When a magnetic filed changes, an emf is induced with a frequency in respect to the change in magnetic flux. Since coil is connected to load, a load current also flows.Here in the picture, the magnet attached to the spin wheel rotates when water hits it. So it creates a change in magnetic flux. This induces a power in the coil connected to the load. Thus the bulb illuminates. You may know that how Electrical/Electronic equipments work. Fundamentals for such device is electric power. Since energy can neither be created,  electric power is generated through the process like conversion of mechanical energy, heat energy, wind energy, light energy, etc. More used method in this world is conversion of mechanical energy. Basically the generating stations are classified according to the fuel used for the generation. Here...
