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
