• Capacitors


  • One of the Big Three Passive Components
  • A two-terminal electrical device that can store energy in the form of an electric charge
  • Constructed out of two metal plates, separated by an insulating material called dielectric
• Resistors


  • One of the Big Three Passive Components
  • A passive electrical component with two terminals that are used for either limiting or regulating the flow of electric current in electrical circuits
  • Main purpose is to reduce the current flow and to lower the voltage in any particular portion of the circuit
• Diode


  • A semiconductor device that essentially acts as a one-way switch for current
  • Allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction
  • Also known as rectifiers because they change alternating current (ac) into pulsating direct current (dc)
• Anode


  Electrode where oxidation reaction takes place, electrons are getting released into the external circuit
• Cathode


  Electrode where reduction reaction takes place, cathode gains electrons from the external circuit
• Transistors


  • A type of semiconductor device that can be used to conduct and insulate electric current or voltage
  • There are three terminals: Base (used to activate the transistor), Collector (positive lead), Emitter (negative lead)
• Inductors


  • One of the Big Three Passive Components
  • Mostly used to decrease or control the electric spikes by storing energy temporarily in an electromagnetic field, and then releasing it back into the circuit
• Switches


  • An electrical device, usually electromechanical, used to control continuity between two points
  • Used to turn electric circuits ON and OFF and to switch electric circuits
• Light Bulb


  • Electric lamp consisting of a transparent or translucent glass housing containing a wire filament (usually tungsten) that emits light when heated by electricity
• Incandescent


  • Typically consists of a glass enclosure containing a tungsten filament
  • Incandescence is the emission of electromagnetic radiation (which includes visible light also) from a hot body as a result of its high temperature or glowing due to heat
• Halogen


  • An incandescent lamp consisting of a tungsten filament sealed in a compact transparent envelope that is filled with a mixture of an inert gas and a small amount of a halogen, such as iodine or bromine
• Fluorescent


  • Consists of a glass tube filled with a mixture of argon and mercury vapor
  • Metal electrodes at each end are coated with an alkaline earth oxide that gives off electrons easily
  • Produces light by the fluorescence of a phosphor coating
• LED


  • Light-emitting diode
  • Widely used standard source of light in electrical equipment
  • When current passes through an LED, the electrons recombine with holes emitting light in the process
• Battery


  • Batteries and similar devices accept, store, and release electricity on demand
  • A device that stores chemical energy and converts it to electrical energy
• Cell


  • A single unit of device that converts chemical energy into electrical energy
  • Battery is a collection of cells that converts chemical energy into electrical energy
• Wire


  • Used for establishing electrical conductivity between two devices of an electrical circuit
  • Transmits electrical power or signals from one point to another
• Power Supply


  • An electrical device that supplies electric power to an electrical load
  • Main purpose is to convert electric current from a source to the correct voltage, current, and frequency to power the load
• Thermistor


  • A resistance thermometer, or a resistor whose resistance is dependent on temperature
  • When an excessively large current flows, it generates heat by itself and becomes highly resistive. With this property, they are used as overcurrent protection devices.
• Voltmeter


  • An instrument used for measuring electric potential difference between two points in an electric circuit
  • An instrument used to measure voltage
• Ammeter


  • A device or instrument that can measure either direct or alternating electric current in amperes that flow in an electric circuit
  • Used to measure an electric current
• Galvanometer


  • One of the instruments for measuring electrical current par excellence
  • Used on electrical circuits to know and measure the intensity and direction of electrical current
• Transformer


  • A device that transfers electric energy from one alternating-current circuit to one or more other circuits
  • Used in electric circuits to change the voltage of electricity flowing in the circuit
  • Used to increase the voltage (called 'stepping up') or decrease the voltage ('stepping down') in AC circuits
• Fuse


  • Fuses are both designed to interrupt the flow of electricity
  • Is likely plugged into the fuse box, through which the building's power is delivered
  • With electricity flowing, the fuse allows the power to pass across the filament and between the related circuits
