1
Describes a concept or an idea using symbols
pictogram
2
A thin and flexible strand that conducts electricity.
Wire
3
The wire is made up of two things:
the copper (conductor of eletricity) and rubber outer layer (insulator)
4
Two or more wires that are connected together aka the splice
joined wire
5
Unconnected or seperated wires, typically wrapped by electrical tape so that the electricity cannot escape
wire not joined
6
To turn electricity on and off meaning that it controls the flow of electricity in a circuit
switch
7
A device that stored and provides electrical energy. Chemical energy gets turned into electrical energy.
Cell or battery.
8
Outlets or sockets, this uses AC where in the direction of the flow of electricity switches back and forth at regular intervals or cycles.
AC voltage source
9
Commonly used at household appliances as it can be easily transmitted at long distances
AC
10
Commonly used in batteries
DC
11
Is a glass object that prevents the electricity from escaping.
Bulb
12
Holds a bulb and provides light when a current passes through it.
Lamp
13
A coiled up wire that creates a magnetic field when electricity passes through it.
Inductor or solenoid
14
A component that limits the flow of an electric current in a circuit
resistir
15
A type of resistor that is used to adjust the level of electric flow in a circuit. An example of it is a dimmer switch on a light fixture.
Rheostat
16
It is used to measure an unknown voltage by comparing it to the known voltage. It is also a type of resistor that has 3 terminals.
Potentiometer
17
In a potentiometer, There is a component that moves a wiper along a resistive element. This movement changes the resistance and voltage in a circuit. Moreover, it is commonly used to adjust volume in audio devices or settings in electronics.
knob/slider
18
It temporarily stores electrical energy. It consists if 2 plates separated by an insulator that resists electricity. It collects and holds the charge which can be then released when needed.
Capacitor
19
It allows the electricity to flow easily in one direction but restricts it to flow in other directions. This component uses DC.
Diode
20
A small electric device that lights up when electricity flows through it. It’s described to be energy efficient and can last a long time. This is also a type of Diode.
LED, light emitting diode
21
A device that converts sound waves to electronic signals. It is used to amplify or record voices. Additionally, it has no vibrating cone.
microphone
22
Small devices that you put into your ears to listen to sounds. It works by receiving an electrical signal from a device in which it can convert it into sound that you can hear.
earphones
23
It plays sound loudly. It converts sound waves to electrical signals. It has a vibrating cone or diaphragm which pushes air to create sound.
loudspeaker
24
It makes sound louder. It works by taking a small electrical signal and boosting its strength so it can drive a loudspeaker and produce louder sounds.
Amplifier
25
A device that changes the voltage of electricity on an AC
transformer
26
Safety device that operates to produce protection against the overflow of electrical circuits
fuse
27
A device that measures the voltage
Voltmeter
28
A device that measures the electric current
ammeter
29
A tool that measures the electrical resistance
ohm meter
30
a device that controls the flow of electricity in a circuit, acting as a switch or amplifier.
transistor
31
device that converts electrical energy into mechanical energy to create motion. It is commonly used to power machines and appliances.
