Triode is a vacuum tube with three electrodes which are cathode, Anode and a control grid. The function of additional third electrode

A Vacuum tube diode is a two electrode vacuum tube as its name shows DI for two ODE for electrodes. The two electrodes are cathode and anode (plate).

This diode was first introduced by Dr. Leo Esaki in 1958. It is called a tunnel diode because due to its extremely thin depletion layer,

A center-tapped rectifier is a type of full-wave rectifier that uses two diodes connected to the secondary of a center-tapped transformer

Opto coupler are designed to provide complete electrical isolation between an input and output circuits.

The operational amplifier or OP-AMP is a direct coupled, high gain amplifier used to perform a wide variety of mathematical operation

Transistor’s within the OP-AMP must be biased so that have the current values of base and collector current and collector to emitter voltages.

The operational amplifier is direct-coupled high gain differential amplifier. The term operational amplifier was originally used for the D.C

A inverting amplifier provides the same function as the common emitter and common-source amplifiers.
