Electricity
Flow of charged particles
1 of 12
Current
Rate of charge flowing
2 of 12
Voltage
Electrical pressure
3 of 12
Hydroelectricity
Generated by falling water where the water can be trapped in resevoirs
4 of 12
Geothermal energy
Heat transferred from hot underground rocks, turns water into steam which can generate electricity in turbines
5 of 12
Natural gas
Cleaner, contains less nitrogen, releases less carbon dioxide
6 of 12
What happens the radioactive energy released from power stations
Sealed into concrete and glass to be buried
7 of 12
Electromagnetic induction
Move a piece of electrical wire in a magnetic field and an electrical current will flow, this is called an induced current
8 of 12
Induced current can be increased by
More turns on the coil, stronger magnets, moving the wire faster
9 of 12
Step up transformer
Increases voltage, decreases current
10 of 12
Step down transformer
Decreases voltage, increases current
11 of 12
