Today January 17,2020 at 2:35 am(IST), ISRO (Indian Space Research Organisation) launched their first satellite of 2020 from French Guiana, by the European Arian-5 rocket.GSAT-30 take place the communication satellite INSAT-4A that complete their 15 years of service from 2005. GSAT-30 is 3,357kg heavy satellite that provide telecommunication service overall India and across the Asia and Australia. GSAT-30: ISRO's Communication Satellite credit : isro.gov.in GSAT-30 provide services for next 15 yeas.It will become ISRO's 24th satellite that launched by the Arian Rocket of ArianSpace which is a commercial arm of European Space Agency (ESA) . ESA is also a long term partner of satellite launching programs of India. ISRO planed more then 20 satellite launching in this year 2020,in which most waited Aditya L1 (ISRO's first mission to study the Sun), Chandrayaan 3 (3rd mission to study moon) and Gaganyaan (ISRO's 1st mission to carry Astronauts in Space).

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...

Imagine a day of sunny summer and you are walking on the road then you are realize the importance of your AC and say thanks to your AC. Air  conditioner work on interesting technology to keep our room chilled. it use some physical laws of thermodynamics to removing heat from the air inside the room. Air conditioner Photo Credit : coolingcitycenter.in Air Conditioner work efficiently to cool the indoor air quickly, but it consume more electric power to do their job. its work under the basic physical laws which says 'the heat is absorbed during the phase transfer of the refrigerant material. Phase Conversion   : the physical state of the material is changes by absorbing the heat from outside atmosphere by virtue of temperature difference between them. this change in physical state by absorbing heat is called the phase conversation or phase transformation.   Example  :  the piece of ice melt on your palm by absorbing heat from you body, absorbed heat...

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...
