3. Electronics is the science of how to control electric energy, energy which the electrons have a fundamental role. Its also deals with electrical circuits that involve active electrical components such as vacuum tubes, transistor, diodes and integrated circuits, and associated passive electrical components and interconnection technologies. You will work with a number of basic electronic components when building electronic circuits, including resistors, capacitors, diodes, transistors, and integrated circuits. Here is a brief overview of the functions of each of these basic electronic components. Basic Electronics Concept:

5. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. Resistor  is an electrical component that reduces the electric current. The  resistor's  ability to reduce the current is called resistance and is measured in units of ohms (symbol: Ω). If we make an analogy to water flow through pipes, the  resistor  is a thin pipe that reduces the water flow. Resistor :

6. A  capacitor  is a device that stores electrical energy in an electric field. It is a passive electronic component with two terminals. The effect of a capacitor is known as capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit. The capacitor was originally known as a  condenser  or  condensator. Capacitor :

7. A  diode  is defined as a two-terminal electronic component that only conducts current in one direction (so long as it is operated within a specified voltage level). An ideal diode will have zero resistance in one direction, and infinite resistance in the reverse direction. Diode :

8. A  light-emitting diode  ( LED ) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor.  Light Emitting Diode : (LED)

9. A  transistor  is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A transistor is a three-terminal device. Namely, Base: This is responsible for activating the transistor. Collector: This is the positive lead. Emitter: This is the negative lead. Transistor:

10. An  inductor , also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. An  inductor  typically consists of an insulated wire wound into a coil around a core. Inductor :

11. An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or "chip") of semiconductor material that is normally silicon. The integration of large numbers of tiny MOS transistors into a small chip results in circuits that are orders of magnitude smaller, faster, and less expensive than those constructed of discrete electronic components.  Integrated Circuits (ICs) :
