Electrical Engineering Flashcards
path for electric components
(electric) circuit
type of generator, which converts mechanical energy (often rotation) into alternating current. It is found in most of the car connected to a rectifier in order to provide powered devices and the battery with DC
alternator
Generally any device that changes, usually increases, the amplitude of a signal
amplifier
electrical storage device consisting of electrochemical cells that transform chemical energy into electricity
battery
passive component with two terminals, and stores electric energy in an electric field
capacitor
safety device which protects an electric circuit from an overcurrent.
fuse
protection around an electric cable, which is insulating against impedance, humidity, dust etc…
jacket
Lightening part of a lamp, which actually converts electricity into light and heat. It is an incandescent part of a lamp in which a tungsten filament or other kind of metal filament wire is heated until it glows to provide light.
lightbult (or simply bulb)
Male electrical connector mounted at the end of a cable in order to match with a female socket and to pro- vide a power device with electricity
plug
electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to con- trol a circuit by a low-power signal (with complete electrical isolation between control and controlled cir- cuits), or where several circuits must be controlled by one signal.
relay
passive two-terminal electrical component that reduces the current flow.
The resistor’s ability to reduce the current is called resistance and is measured in units of ohms (symbol: Ω).
resistor (electric resistor)
Device that detects a physical quantity such as a change (in temperature, proximity, pressure, light intensi- ty) and converts it into a signal which can be read by an observer or by an instrument.
sensor
Female electric outlet into which a plug is put in to provide a power device with electricity. A socket corre- sponds to a definite plug (e.g. 2-pin plug/2-pin socket etc…)
socket
electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupt- ing the electric current or diverting it from one conductor to another.
switch
device, which converts an energy form into any other form e.g. device in which electrical signals are conver- ted to and from other physical quantities (energy, force, torque, light, motion, position, etc.). Sensors and actuators are types of transducers. Thus the term ‘transducer’ can be regarded as an umbrella term.
