P3SUSTAINABLE

ENERGYLesson 6: Generators

OBJECTIVES MUST understand how generators produce electricity

SHOULD understand the need for fuel for electricity generation

COULD understand that power generation needs to conform to standards

KEY WORDS You need to be able to define the

following:Magnetic field GeneratorElectromagnetTurbine

TEXTBOOK ANSWERS1) In power stations.2) A generator has a magnet and coil of

wire, one of which spins relative to the other. 3) Electromagnets can be much stronger

than permanent magnets.4) To provide energy to make turbines

spin.5) To provide more energy for more

generators. 6) The electricity produced at any power

station can be used anywhere, reliably and safely.

WORKSHEET ANSWERSActivity 1 (Low demand)1) By spinning the generator more quickly.2) By spinning the generator more quickly.3) Depending on the generator – may be

the coil or the magnet .Activity 2 (Standard demand)1) Coal, biomass, gas.2) The electromagnet in the middle spins

and is surrounded by stationary copper bars in which the current flows.

3) More is used when a larger voltage is produced.
