- 7. SUPERCONDUCTORS A superconductor is a material that can conduct electricity or transport electrons from one atom to another with no resistance. This means no heat, sound or any other form of energy would be released from the material when it has reached "critical temperature" (Tc), or the temperature at which the material becomes superconductive. 7 Reference: http://ffden-2.phys.uaf.edu/113.web.stuff/travis/what_is.html

- 17. SEMI-CONDUCTORS Semiconductors are those materials whose conductivities lie between conductors and insulators. They have poor conductivity than conductors and higher than insulators. Therefore, they are neither good conductors nor good insulators. When temperature of a semiconductor is increased, its resistivity decreases or conductivity increases. At higher temperature, a semiconductor conducts better. Therefore ,the semiconductors have negative temp coefficient of resistance. 17
- 22. 22 DIELECTRICS A dielectric material (dielectric for short) is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization.

- 27. 27 ACTIVE COMPONENTS Active components are components that can be generate amplify and even controls the current in a circuit Reference: Slideshare.com
- 28. 28 TRANSISTOR A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power.
- 29. 29 CIRCUIT An electronic circuit is composed of individual electronic components, such as Resistors Transistors Capacitors Inductors Diodes
- 30. 30 LOGIC GATES A logic gate is an elementary building block of a digital circuit. Most logic gates have two inputs and one output. At any given moment, every terminal is in one of the two binary conditions low (0) or high (1), represented by different voltage levels.
- 31. 31 PASSIVE COMPONENTS Passive components are components that do not generate voltage but controls the current in a circuit. Reference: Slideshare.com
- 32. 32 RESISTOR A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors act to reduce current flow, and, at the same time, act to lower voltage levels within circuits. In electronic circuits, resistors are used to limit current flow, to adjust signal levels, bias active elements, and terminate transmission lines among other uses.
- 33. 33 CAPACITOR capacitors special is used to store energy; they’re like a fully charged electric battery. Caps, as we usually refer to them, have all sorts of critical applications in circuits. Common applications include local energy storage, voltage spike suppression, and complex signal filtering.
- 34. 34 INDUCTORS An inductor, also called a coil or reactor, is a passive two- terminal electrical component which resists changes in electric current passing through it. It consists of a conductor such as a wire, usually wound into a coil. When a current flows through it, energy is stored temporarily in a magnetic field in the coil
- 35. 35 DIODES A diode is a specialized electronic component with two electrodes called the anode and the cathode. Most diodes are made with semiconductor materials such as silicon, germanium, or selenium. Diodes can be used as rectifiers, signal limiters, voltage regulators, switches, signal modulators, signal mixers, signal demodulators, and oscillators.
