Active components:
Active components or devices used in electronic circuits are numerous but all of these active components or devices can be broadly classified into two categories-tube type and semiconductor type devices. Tube devices can be further divided into two categories -vacuum tubes(such as vacuum diode,vacuum triode,vacuum tetrode and vacuum pentode)
and gas tubes.
semiconductor devices include junction diode,bipolar junction transistor(BJT),field effect transistor(FET),uni junction

Passive components:
passive components include resistors,inductor and capacitors,these components are split into two categories:those which dissipate energy and those which store it. in the latter category is the inductor,which stores energy by virtue of a current passing through it, and the capacitor,which stores energy by virtue of a voltage exiting across it. The third components, the resistor ,is the only one of the virtue of a voltage exitsing across it.
