	Electric Circuits

Are you very familiar with electricity. How much do you know about Electric circuits. Do you know how they work? And the different types? Here is an activity to help you learn a bit more about them. All you have to do is read the information on this website and then answer the questions below in your notebook or worksheets.

QUESTIONS

A BASIC ELECTRIC CIRCUIT:

What are the basic elements of an electric circuit?

Describe a complete circuit and how it works.

A circuit has got at least two basic devices. What are they?

A SERIES CIRCUIT:

What is a series circuit?

What happens to the two lights when the wire is broken? Why?

A PARALLEL CIRCUIT:

In a parallel circuit with three light bulbs, what happens to the other light bulbs when one is broken? Why?

What is the difference between a series circuit and a parallel circuit? Which one do you think is better?

FINAL REVIEW:

Finally, fill in the gaps with the correct word. If you need help, you may try this simple game.

A ________________ is a complete path, around which electricity can flow.

A ________________ circuit is a path which forms one continuous loop; there can be one or more devices in the path. If a wire breaks, the entire circuit stops working.

A ________________ circuit is a path that branches; the electricity can follow more than one branch, just like a river that splits into several paths. Each path can have its own switch. If one of the paths breaks, the others will still work.
