Electricity Batteries, Current, Circuits, and More!
Insulators and Conductors • What parts of an automobile conduct and do not conduct electricity when struck by a fallen power line? • What should you do and why?
Producing Electrical Energy • Which of the devices is our main source of electrical energy? • What is the source of electricity in an automobile? • What was the source of electrical energy in the Skylab space station?
Dry Cells and Batteries • On the dry cell, where are the contact points? Which way do the electrons flow? • Why aren’t the separators in a storage battery made of metal? • How is a 9 volt battery different than a 1.5 volt battery from the picture?
Circuits • List the items needed to make a complete circuit of electricity. • What causes a short circuit?
Series and Parallel Circuits • Which type of circuit would you find in homes? Why?
Switches and Fuses • What do you know about push button switches and circuit breakers?
An Electric Motor • Which parts of the electric motor have magnets? • How are a generator and a motor alike? • How are they different?
An Electric Motor • Electric motors operate due to the attraction and repulsion of the magnetic poles of the armature and the field magnet.
Devices Using Electricity • How are the incandescent light and the fluorescent light different? • What do you think were some of the problems Thomas A. Edison had in inventing the incandescent lamp?
Current Electricity Extras • What do AC and DC stand for? • What’s the difference between AC and DC electricity? • Where do you find them and what are their advantages?
