Circuits
Components
Cell
A single unit of power and is used to convert chemical energy into electrical potential energy, allowing a current to flow
Diode
A semiconductor diode will only allow the current to flow in one direction, and they are used to convert an alternating current to a direct current.
Battery
A collection of cells, and is used to convert chemical energy into electrical potential energy, allowing a current to flow
LED
Used to convert electrical energy directly into light energy, minimising energy waste.

LDR
The resistance of a LDR depends on the light intensity. If there is a high light intensity, then the resistance is low, however, if there is a low light intensity, the resistance is high.
Fuse
Used to break when the current is too high, cutting the circuit, and protecting appliances from damage.
Thermistor
The resistance of a thermistor depends on the temperature. If there is a high temperature, then the resistance is low, however, if the temperature is low, then the resistance is high
Ammeter
The device used to measure the electricity in a circuit. The amount measured is expressed in amperes
Ohmic Conductor
The current is directly proportional to the potential difference. It is a straight line when kept at a constant temperature
Voltmeter
The device used to measure the voltage in electrical circuits. The amount measured is expressed in volts

Filament Bulb
A common type of light bulb that contains a thin coil wire made from filament. It heats up when the electrical current flows through it, causing it to light up
Circuits
-
-
When the electrons arrive at the component, electrical energy is transferred.

-
If the wire becomes thinner, the length increases, or there is an increase in metal ions, then it takes the electrons longer to complete the circuit, this is the change in resistance.
