Electronic Equipments or Components:
Nowadays every person want to use electronic devices and for these devices, electronic components are very essential part. There are various electronic equipment in the world for building an electronic circuit. Now we can see, what is electronic components: An electronic component is a basic electronic device in the electronic system. There are two types of components, first is passive components,and second is active components the name given as active components because it should take part in the transformation of energy, while passive components should store energy. Detail information of all components is bellowed:
PASSIVE COMPONENTS:
1. Resister:
A resister is a passive two-terminal electrical component which is mostly used in electronic circuit. As the name indicates that it to resist or oppose the flow of current, this opposition to the current flow is called as resistance of the resister. Symbolically it is denoted by"R". According to Ohm's law V=IR that is voltage is directly proportional to the current flowing through it. Resistor is used to control the voltages and the currents in your circuit. Its unit is Ohm(Ω). Resister is classified into different categories like fixed resister, variable resister, etc.

2. Capacitor:
Capacitor is two terminal passive electrical components, which is made up of two conductive plates, the insulator is sandwiched between them. Capacitor is used to store energy in the form of an electric field. This ability to store charge in plates is called capacitance. Symbolically it is represented by "C". Mathematically, the stored charge Q=CV, where C is capacitance and V is voltage. Its unit is Microfarads(uF). Capacitor is classified into different categories like ceramic capacitor, film capacitor, variable capacitor, etc.

3. Inductor:
Inductor is two terminal passive electrical component, It is a simple coil of wire, which store energy in the magnetic field. It opposes the change in current. Its unit is Henry. Inductance L=(μKN2.S)/l where, L is inductance, μ is magnetic permeability, K is a magnetic coefficient, N is the number of turns of coils, S is the cross-sectional area of the coils, and l is the length of the coil in an axial direction.

ACTIVE COMPONENTS:
1. Diode:
A diode is a two-terminal device i.e. anode and cathode, the anode is a positive terminal, and the cathode is the negative terminal. A diode allows current only in one direction, when the positive voltage is applied to the anode and negative voltage is applied to cathode then current flows and voltage is reversed then it blocks the current. It is mostly used to convert alternate current into direct current. There are different types of diodes like PN junction diode, Zener diode, Schottky diode, etc.

2. Transistors: Transistor is three-terminal (Base, Emitter and Collector) semiconductor device mostly used as a switching device and amplifier.when a small amount of current flowing from base to emitter the it will turn on otherwise remains off.

4.Integrated circuits:
Integrated circuits are made up of multiples small components such as thousand of tiny resistors, capacitors and transistors are fabricated which can not be separated.
