Light, electric circuits and equipment!!!!! Flashcards
ammeter
An ammeter is a measuring instrument used to measure
electric current in a circuit.
Strommesser,
Ampèremeter
amplifier
→ to amplify = to boost
An amplifier is an electronic device for increasing the
amplitude of electrical signals
Verstärker
→ verstärken
array
→ antenna array
→ photovoltaic array
Although a PV array produces power when exposed to
sunlight, a number of other components are required to
properly conduct, control, convert, distribute, and store the
energy produced by the array
Feld, Aufstellung,
Bereich
→ Antennengruppe
→ PV-Reih
cap
A light bulb is mounted on a cap
Lampensockel
capacitor
A capacitor is used to store energy
Kondensator
charge
→ to (re)charge
→ to discharge
Current is the rate of flow of electric charge in a circuit.
Batteries run down with usage and need to be recharged
Ladung
(→ wieder auf-)laden
→ entladen
component
A circuit board consists of many electronic components,
such as relays and resistors
Komponente, Bauteil
conductor
→ to conduct
A conductor transmits electricity, heat or light.
Leiter
→ leiten
cord
→ cordless
Most electrical appliances have a cord to connect to a
socket.
Kabel
→ kabellos
electric circuit
An electric circuit is a system of electrical conductors and
components forming a path.
elektrische Schaltung,
Stromkreis
to emit (light)
→ light-emitting diode
→ emitter
An LED emits light very efficiently. A light-emitting diode
(LED) lets current pass in one direction only.
The emitter and collector are parts of a transistor.
absondern, ausstrahlen
→ Leuchtdiode,
lichtemittierende Diode
→ Emitter
filament
In light bulbs, an electric current passes through a thin
filament wire, heating it until it produces light.
Glühdraht
fluorescent lamp
→ compact fluorescent
lamp (CFL)
A fluorescent lamp is a gas-discharge lamp which uses
electricity to excite mercury vapour.
→ In colloquial English, a compact fluorescent lamp is an
energy-saving lamp.
Leuchtstoffröhre
→ Kompaktleuchtstofflampe,
Energiesparlampe
fuse
→ the fuse blows
→ fuse box
Fuses are used in electrical systems to protect against
excessive current. A fuse blows if excess current flows.
elektrische Sicherung
→ durchbrennen
→ Sicherungskasten
(power / electrical) grid
→ off-grid
An electrical grid is an interconnected network for
delivering electricity from suppliers to consumers
Stromnetz
→ netzunabhängig
illumination = lighting
→ to illuminate = to
light
LEDs are used for power-efficient street illumination.
Beleuchtung
→ beleuchten
insulator
→ to insulate
→ insulation
An insulator is a material that resists the flow of electric
currents, such as porcelain.
Isolator, Nichtleiter
→ (ab)isolieren
→ Isolierung
light bulb
In 1872, Lodygin, an electrical engineer, was one of the
inventors of the incandescent light bulb.
Glühbirne
plug
All electrical devices have plugs to connect them to the
power grid.
Stecker
pylon
Electricity pylons are used for carrying power lines high
above the ground.
Hochspannungsmast
rectifier
→ to rectify
A rectifier is an electrical device that converts AC to DC
Gleichrichter
→ demoldulieren,
gleichrichten
relay
A relay is an electrical device that is activated by a current
in one circuit to open or close another circuit.
Schaltrelais
resistor
A resistor is a two-terminal electronic component that
produces a voltage across its terminals.
elektrischer Widerstand
socket
British sockets have 3 slots
Steckdose
to step up/down
In substations, the voltage is stepped down to lower voltage
levels
(hier:) transformieren
switch
→ to flick a switch
A switch is an electrical component that can make or break
an electrical circuit. One flicks it to interrupt the current.
Schalter
→ einen Schalter
umlegen, betätigen
thermistor
A thermistor is a type of electrical resistor whose resistance
varies significantly with temperature
Heißleiter
visible
→ visibility
invisible
The visible spectrum is the portion of the electromagnetic
spectrum that is visible to the human eye
sichtbar
→ Sicht, Sichtbarkeit
unsichtbar
voltage
Voltage is commonly used for denoting electrical potential
difference
Spannung
wattage
The amount of current required by an electrical appliance
depends on the wattage.
Wattzahl, Wattleistung
wavelength
→ wavelength range
Electromagnetic radiation in the visible range of
wavelengths is called visible light.
Wellenlänge
→ Wellenlängenbereich
wire
→ wiring
→ live wire
→ neutral wire
→ earth wire
The international standard colour for live wires is brown,
neutral is blue and protective earth (ground) is green and
yellow.
A live wire is one through which current flows into a device.
Live also means a circuit is energized, i.e. that current is
flowing around the circuit.
Draht, Kabel
Verkabelung,
Verdrahtung
→ stromführender Draht
→ Null-/Mittelleiter
→ Erdungsleiter
