Is Your House Plumbed For Electricity?
Ever wonder why electricity is always there waiting in the wire for you to use? A good way to understand it is to compare household electricity to household plumbing. Turn a faucet handle and out pours the water. Why? Because there is:
 |
A supply of water somewhere |
|
A pipe to carry the water |
|
A pressure difference between the water supply and your faucet |
|
A faucet to turn the water on and off |
Compare this to how you get electricity to a lamp. In this case, there is:
|
A power plant to supply moving electrons |
|
Wire to conduct the moving electrons |
|
More moving electrons at the power plant than in your lamp |
|
A switch to turn the current on and off |
