electronics introduction

Electronics ------------- electronics is the branch of engineering which deals with the behavior of electrons in a material and application in our necessary field. the current and electricity is due to the movement of electrons in a conductor. the materials and devices made from the useful behavior of electron motion are called electronics devices. for example resistor, capacitor, inductor, diode, transistor, intigrated circuits and micro controller. the instruments which use these component to carry out some tasks are called electronic appliances. so the field of electronics engineer is to design electronics device and appliance. computer, television, radio, dvd, mobile and all other appliances conducting from electricity are electronics appliances.
