Welcome to" Tech Electrical Master" Knowledge about Electrical Devices.

This blog is authored and maintained by a group of Engineers having vast experience in Electrical, Electronic,  Digital Technology.  You may contact them with your queries via an shivpalsain002@gmail.com

Electricity is one of those discoveries that have changed the daily life of everybody on the planet. Electricity is the key component to modern technology and without it most of the things that we use everyday simply could not work, and would never have been created. Our mobile phones, our computers, the Internet, our heating systems, our televisions, our light bulbs, our complex medical equipment  – nearly everything in the world depends upon the power to keep them running.

“Tech Electrical Master" is a significant electrical/electronics  information resource for electrical/electronics field professionals , college /school going students across the world which offers brief and conceptual information based upon theoretical as well as mostly practical experience.

Our aim is to transfer knowledge and help others to make better ambiance so that every individual can grow with the growth of society . This blog is dedicated to knowledge sharing. The society and technology can excel only when there is a proper source of knowledge. So, for this ,it’s just a trial to share my own experience and knowledge about electrical/electronics information and its challenges, among the common mass.

What is Capacitor,its principle ,SI units

What is Capacitor:-  Capacitor is a electronic  device that stores electric charge.Two metal  plates ,separated by an insulator constitute a capacitor or condenser.The plates accumulate electric charge when connected to power source.The plates are made of a conductive materials like-aluminum, silver,tantalum etc.

Capacitor

How capacitor work:- A capacitor is made of two metallic plates, with a dielectric material in between the plates. When you apply a voltage over the plates,a capacitor works by storing energy electrostatically in an electric field.

Basic Configration

Principle of a capacitor:- A capacitor  works on the principle that the capacitance of  a conductor is brought near it.A capacitor has two plates separated by a distance having equal and opposite chares.

SI Units :-  SI units of capacitance is Farads.

                              C= Q/V

Capacitor in series:- When negative plates (-ve) of one capacitor connected with positive (+ve) plates of another capacitor then we can say that capacitor are connected in series.

                                 1/C =1/C1+1/C2+1/C3

       

Capacitor in parallel:-When one plate of each capacitor is connected to the  positive (+ve) terminal of the supply mains and the another  plate of  each capacitor to the negative (-ve) terminal.

                                         C=C1+C2+C3

                

                        

what is Resistor

A resistor is an electrical componenets that limits or regulates the electrical current in an electronics  circuit.we can say also that a resistor is an electrical components that limits the flow of electrical current.......
                       The resulating current is inversely proportional to the resistance. This is defined in ohm's law ,which states that the current(I) is equal to the voltage (V) divided by the resistance (R).
                                 
                                                                      I= V/R

If too little current is flow in component, it may not operate.If too much current is allowed through, it can damage the component.Therefore resistor play an important role in an electronic circuit.
Sevral type of resistor exist ,but most are made of carbon and an insulating matrial,such as ceramic.

NOTE:- Resistor are represented in circuit diagrams by jagged line.They are usually labeled R1,R2,R3 ect.

what is Transformer

A transformes is static devices which consists of two or more stationary electric circuits interlinkerd by a common magnetic circuit for the purpose of transforming electrical energy between them.

The transfer of energy from one circuit to another takes place without a change in frequency.In modren  electrical distrubution system, transformer are used  to boost voltages levels so as decrease line losses during transmission.
