ESSAY:
List two ways magnets can be used to produce electricity
- By moving a magnet through a coil of wire
- By moving a coil of wire through a magnetic field
ESSAY:
What is all matter made up of?
small particles with an electric charge
ESSAY:
Would it be better to have all the outlets and the lights wired in a parallel circuit or series circuit?
A parallel circuit so that all the outlets and lights can turned off individually.
