Q

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.

An insulator is a material that resists the flow of electric
currents, such as porcelain.

A

Isolator, Nichtleiter
→ (ab)isolieren
→ Isolierung

18
Q

light bulb
In 1872, Lodygin, an electrical engineer, was one of the
inventors of the incandescent light bulb.

A

Glühbirne

19
Q

plug
All electrical devices have plugs to connect them to the
power grid.

A

Stecker

20
Q

Electricity pylons are used for carrying power lines high
above the ground.

A

Hochspannungsmast

21
Q

rectifier
→ to rectify
A rectifier is an electrical device that converts AC to DC

A

Gleichrichter
→ demoldulieren,
gleichrichten

22
Q

relay
A relay is an electrical device that is activated by a current
in one circuit to open or close another circuit.

A

Schaltrelais

23
Q

resistor
A resistor is a two-terminal electronic component that
produces a voltage across its terminals.

A

elektrischer Widerstand

24
Q

socket
British sockets have 3 slots

A

Steckdose

24
Q

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.
