Definition: 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, divide voltages, bias active elements, and terminate transmission lines, among other uses.
Some types: Shunt, Wire-wound, thick and thin film, Fixed, Variable (Potentiometer), Varistor, Thermistor, Carbon Film, Cement, Metal-Oxide, Cermet, and Fusible
A few applications: Heaters, radios, toasters, TVs, and Cellphones
Definition: 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.
Some types: Air Core, Iron Core, Ferrite Core, Iron Powder, Laminated Core, Bobbin Based, Toroidal, Multi-layer Ceramic, Film, Variable, Coupled, and Molded
A few application: Filters, Sensors, Transformers, Motors, and Energy storage
Definition: Snap Disc, or Snap switch thermostats are bimetal mechanical thermostats that function via the thermal expansion and contraction of a bimetal disc that "Snaps" from a convex to a concave shape at a set temperature
A few applications: Electrical devices, Thermometers, Thermostats, Clocks, Ovens, Florescent light starters, and Circuit Breakers
Definition: A device or substance for absorbing excessive or unwanted heat.
Some types: Extruded, Bonded, Skived, Stamped, Forged, CNC Machine
A few applications: Electrical appliances, Fridges, Cars (Radiator), TVs, Radios, and computers (pretty much anything that makes unwanted heat)
Definition: A capacitor is a passive two-terminal electronic component that stores electrical energy in an electric field. The effect of a capacitor is known as capacitance
Some types: Ceramic, Surface mount, Electronic, Polar, Audio, Tantalum, Paper, and Electrolytic
A few applications: TV's, Computers, Radios, and Power supplies
Definition: A diode is a two-terminal electronic component that conducts current primarily in one direction; it has low resistance in one direction, and high resistance in the other. A thermionic tube has two electrodes (an anode and a cathode).
Some types: Zener, Rectifier, Mosfets, Gunn, LED, Pin, Step Recovery, Laser, Photo, Tunnel, Varacter, and Schottky
A few applications: Computers, TVs, Radios, and Phones
Definition: An integrated circuit or monolithic integrated circuit is a set of electronic circuits on one small flat piece of semiconductor material that is normally silicon.
Some types: Digital, Analog, Mixed, Logic, Comparators, Switching, Audio Amplifiers, Operational Amplifiers
A few applications: Anything that processes information (TVs, Computers, Etc.)
Definition: A seven-segment display, or seven-segment indicator, is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays.
Some types: Common Cathode Display and Common Anode Display
A few applications: Numerical Displays (Alarm Clocks, Timers, and Calculators)
Definition: An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave. Oscillators convert direct current from a power supply to an alternating current signal.
Some types: Armstrong, Crystal, Hartley, RC Phase Shift, and Colpitts
A few application: TV, Radio, Audio and Visual systems, and other communication devices
Definition: A Voltage Regulator is a system designed to automatically maintain a constant voltage level. A voltage regulator may use a simple feed-forward design or may include negative feedback
Some types: Linear and Switching
A few applications: Power supplies, appliances, automobiles, computers, and TVs
Definition: A rectifier is an electrical device that converts alternating current, which periodically reverses direction, to direct current, which flows in only one direction. The process is known as rectification, since it "straightens" the direction of current.
Some types: Uncontrolled, Half-controlled, and Full-controlled
A few applications: TVs, computers, adapters, and cars
Definition: A semiconductor device with three connections, capable of amplification in addition to rectification, and able to switch electronic signals and electrical power
Some types: NPN and PNP
A few applications: Cellphones TVs, Calculators, Computers, Radios
