Resistance: Definition, Symbol,Working Principle, Use of It

Image
     When we apply electric potential across any conductor, bulb or heater coil then electric  current flows through it but when electric current starts flowing through the conductor the conductor material opposes the flow of electric current. The reason why any conductor opposes flow of  electric current is known as resistance. Because of it when current flows through  any conductor it produces some heat.Every material has its own nature toward electric potential. On the basis of their behaviour in electrical material they are divided into three parts. Conductors( this type of materials have low resistance. It is used for making wire and coils.) Semiconductor (this type of materials have resistance more than conductor but less than Insulators.) Insulators (this type of materials have high resistance. Such type of materials are not flow of electric current through itself. ) In this article we know more about resistance and resistor  Table of conte...

Direct current :- Definition, Sources and Difference between A.C. and D.C.

  1.Introduction to Direct current :- Direct current always flows in one direction from positive terminal to negative terminal.In a given circuit the direction of current is from ABCDA.Main source of Direct current is cell/battery and D.C. generator but today we use a.c. in our house and offices more. 2.History of Direct current (Historical Development) :-  The development of direct current was done by Italian physicist Alessandro  Volta In 1800. Alessandro Volta developed a voltaic pile   which is also known as the first electric battery.  H.V. D.C.(High voltage Direct current) transmission system developed in 1950s which is used in long distance transmission nowadays.Because it is economical for long distance transmission.    American scientist Thomas Alva Edison developed low voltage direct current incandescent lamp(bulb) for home and offices  in 1882.   3. Basic concepts of Direct current :-  When d.c. Voltage is applied acr...
