Diodes, rectifiers
Diode is 2 terminal device used in electronic devices. Diode conducts current in one direction and block in other. it is commonly used as rectifier and reverse current flow protection in a circuit. Subset of Diode is Zener diode and it is used for voltage regulation in electronic circuit.
A bridge rectifier is an arrangement of four or more diodes in a bridge circuit configuration which provides the same output polarity for either input polarity. It is used for converting an alternating current (AC) input into a direct current (DC) output. A bridge rectifier provides full-wave rectification from a two-wire AC input, therefore resulting in lower weight and cost when compared to a rectifier with a 3-wire input from a transformer with a center-tapped secondary winding. -

Capacitors
A capacitor is a passive electrical component whose characteristic feature is capacitance. In addition, each real capacitor exhibits other, so-called parasitic properties, such as inductance and resistance, which distinguishes it from a capacitor, which is intended to be an ideal component that has only a capacitance that is also constant and independent of ambient conditions.
Capacitor principle:
The capacitor consists of two conductive plates (electrodes) separated by a dielectric. Electric charges of opposite polarity are applied to each of the plates, which are attracted to each other by an electric force. The dielectric between the plates does not allow the charged particles to come into contact, thereby neutralizing or otherwise discharging the electric charges. At the same time, the dielectric reduces the strength of the electric field of the charges on the plates by its polarization and thus allows the placement of a larger amount of charge. -
Led
LEDs
LED (Light-Emitting Diode) is a semiconductor electronic component that has the ability to emit light, or infrared or ultraviolet radiation. This is different from standard diodes. It is an electronic semiconductor device containing a PN junction. The official Czech name is electroluminescent diode. Furthermore, it is possible to come across names such as light emitting diode, light emitting diode, occasionally fluorescent lamp. Slang is called saltpeter. -

Potentiometers
Potentiometers are very useful in changing the electrical parameters of a system. It is a resistive type potentiometer which you can use to change RC constant of a circuit, changing the voltage level at comparator, changing the audio output volume, changing the brightness of any LCD screen, even measuring the rotary movement if it is used as a transducer, controlling the precise movement of servo motors and other control applications.

Resisters
A resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element
-
Voltage regulators
The purpose of a voltage regulator is to keep the voltage in a circuit relatively close to the desired value. Voltage regulators are one of the most common electronic components since a power supply frequently produces a raw current that would otherwise damage one of the components in the circuit.

Transistors
Transistor is a 3 terminal electronic device used for switching or amplify electronic signals. Transistor is a basic building block of electronic devices. It is also known as BJT Bipolar Junction Transistor. Two type of construction classify them as P-N-P transistor and N-P-N Transistor.

Mosfet
The Metal Oxide Semiconductor Field Effect Transistor (MOSFET, MOS-FET, or MOS FET) is a subset of field-effect transistor (FET). It has an insulated gate, whose voltage determines the conductivity of the device. This ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals. A metal–insulator–semiconductor field-effect transistor or MISFET is a term almost synonymous with MOSFET. Another synonym is IGFET for insulated-gate field-effect transistor.
MOSFET is a voltage driven switching device unlike BJT which is current based switching device. The main advantage of a MOSFET is that it requires almost no input current to control the load current, when compared with bipolar transistors. In an "enhancement mode" MOSFET, voltage applied to the gate terminal increases the conductivity of the device. The MOSFET is by far the most common transistor in digital circuits, as hundreds of thousands or millions of them may be included in a memory chip or microprocessor. Since MOSFETs can be made with p-type or n-type semiconductors, complementary pairs of MOS transistors can be used to make switching circuits with very low power consumption, in the form of CMOS logic. -

Varistors
Varistors are voltage dependent, nonlinear device which have an electrical behavior similar to back-to-back zener diodes. Zinc oxide varistor are nonlinear resistors, consisting main of zinc oxide and several kinds of metal oxide additive. They are bilateral and symmetrical V-I characteristics curve and unparalleled large peak current capability are used for absorption of transient voltage, suppression of pulse noise and circuit voltage stabilization.
