  • 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
