Electricity Flashcards
Magnet
A piece of metal that attracts other materials.
Magnetic material
Materials that are attracted to magnets e.g iron,cobalt,nickel.
Alloy
A mixture of two metals. Steel containers iron and cobalt.
Distance-time graph
Graph drawn using time on x axis and distant on y axis. The slope gives speed
Distance:
Length between two points. Unit is meters (m)
Speed.
Distance travelled divided by time taken (m)
Time.
How long it takes to do something.
Current electricity.
It’s a steady flow of charge through wires and circuits.
Static electricity.
Involves electric charge collecting in one place and suddenly it jumped from one place to another.
Components.
The objects in a electrical circuit e.g. bulb ,speaker.
Circuit diagram.
A drawing using symbols to represent how a circuit is set up
Current.
The rate of flow of charge per second symbol is (I). Measured using an ammeter.
Ammeter
Equipment used to measure current.
Acceleration
When speed changes over time ,it is called acceleration
