Electricity unit contest

Hey Science 9 bloggers!

In the next unit, we will be learning about electricity. Throughout the unit, you will be learning about Voltage, Current, Resistance, and Power.

The contest: post (as comments to this post) as many Voltage, Current, Resistance, or Power values of various electrical appliances that you use in your home.

The rules: You must include the name of the electrical appliance in your comment. Anything from a hairdryer to an Ipod is acceptable. If you can only find one value, that is acceptable...post it as a comment anyways. There may only be one comment for one appliance; first one to comment gets a point for that appliance. You must include the units in your comment as well. (example of a comment hairdryer 1000 W or 1000 Watts)

You should find the information you need on the back or bottom of whatever you are looking at. If it has a battery, sometimes you can find the information you need on the battery itself (example: cordless phone battery packs have Current and Voltage listed on the battery itself; you have to take out the battery pack to see this information).

Good luck!

PS: there may be a prize at the end of this contest.
