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
