1. Measuring Current

2. Voltage The force that pushes the electrons through the wire.
More voltage= more energy and more current

3. Resistance
Something that slows down the flow of electrons through a wire.

4. What effects resistance?
Thickness- The thicker the wire, the better electrons can move freely.

5. What effects resistance?
Length: The shorter the wire, the better

6. What effects resistance?
Temperature: The colder the wire the better the electrons can move freely.

7. What effects resistance?
Type of Metal: copper is the best.
