How Inverter Works | What is Inverter | AC and DC current | Electrmagnetic induction | Type of inverter |

We can't imagine a our life without electricity. its become basic need of everyday life. the electronic devices like smart phone, T.V, A.C , electric moter and many more consume lots of electricity. just imagine a day without electricity, we could not use the any kind of electronic device. the electricity is fuel of our daily used appliances. there are two different types of electricity used in our houses and offices. these two types are Alternating current (AC)  and Direct current (DC) . let understand these both types of electricity in brief AC (Alternating Current) is a type of current that flows in both directions positive and negative, and continuously change it direction about 50 to 60 time in a second. since its continuously change their direction hence its called the alternating current. DC (Direct Current) is that type of current which flows in only one direction either positive or negative. it doesn't change their direction with time. since its flows i...

Induction cooking | Working theory | Health and Sefty | How induction cooktop work |

Induction cooking is the the amazing technology, it helps in providing efficient heating instead of old method like flame or heating element. its work on the theory of electromagnetic induction . induction cook top In above picture there are an induction cook top having an multitasking key panel and several keys for different work. it is safer and efficient then any old cooking method. heating can control easily by this. induction cooking works on the principle of electromagnetic induction, hence its produce heat only in pot placed over top. Working theory of induction cooking : Induction heating The induction produce a large heat in the cookware and reduce the time of cooking. its only supports the ferromagnetic cookware, or the cookware having a metallic plate at the bottom. the cook top works on the electromagnetic induction principle.  Electromagnetic induction is the process in which the electric current produce in the circuit due to change in magnetic f...

What is Holography | Basic Principle of Holography | Sci-Talks | Shivam Dhyani

 What is Holography Holography is a technique that enables a wavefront to be recorded and later reconstructed. Holography is best known as a method of generating three-dimensional images, but it also has a wide range of other applications. In principle, it is possible to make a hologram for any type of wave. Gabor, who invented holography in 1947, introduced the term using two Greek words: “Holos” - whole and “Graphe” - writing. It simply means that the recorded holographic image of the object contains whole optical information about the object – Amplitude and Phase information of the light scattered from the object. Ideally, the hologram is a three-dimensional image reproduced from an interference pattern recorded by coherent light beans and holography is a process of reconstructing and writing a hologram.      White light from the sun or a light bulb is a combination of every color of light in the spectrum, which is not useful for a hologram. However, a laser shine...
