Summary

Electronics is the branch of technology that deals with the use of components to control the flow of electricity. Most of electronic components are made of semi-conductors. Electronic circuit is a closed conducting path through which an electric current either intend to flow or flows. N-type semiconductor has more electrons (negative charge) than holes (positive charge). P-type semiconductor has more holes (positive charges) than electrons (negative charges). P-N Junction diode is an electronic component in which p-type semiconductor is combined with an n-type semiconductor. Capacitor is an electronic component whose function is to store electrical charges.
