Application of PN junction diode

The PN junction diode has the following important applications are given below, PN junction diode is used as a voltage doubler, tripler, quadrupler in voltage multiplier circuits. It is used as a rectifier in DC power supply.

V-I characteristic of tunnel diode

It immediately conducts the diode when forward biased voltage is applied. The current is increases to its peak point value (Ip). The diode currents starts decreasing till it reaches its minimum value called valley point current (Iv)

What is tunnel diode?

The tunnel diode was first introduced by Dr. Leo Easki in 1958. The Tunnel diode is high conductivity two terminal PN junction diode. It is heavily doped PN junction diode in which voltage increases and the electric

Application of light dependent resistor (LDR)

The Light Dependent Resistor (LDR) used for automatic contrast and brightness control in television receivers. The LDR is used in the infrared astronomy. The LDR is used in optical coding. Used in light activated control circuits. Used

Construction of PIN diode

The PIN diode is a diode with a wide, it lightly doped intrinsic semiconductor region between a p- type semiconductor and an n-type semiconductor region. This region normally heavily doped as they are used for ohmic contacts.

Some of the important applications of LED  are given below: It is used in optical switching application. It is used in burglar alarm system. It is used for indicating power ON/OFF conditions, power level indicators or stereo

Advantages & disadvantage of optical fiber

Advantages of optical fiber : The optical fibers have greater information carrying capacities than metallic conductors. The optical fiber are lighter and smaller.The optical fiber cables are cheaper to transport and easier to install than metal cables.

Thermistor or Time dependent resistor (TDR)

The word thermistor is a contraction of the term thermal resistor. Thermistor is also known as temperature sensitive resistor or temperature dependent resistor (TDR). It is a type of resistor whose resistance is dependent on temperature. Thermistor
