Principles of Physics. So far, we’ve talked about non-moving charge We know that charged objects :  exert an electrostatic force on each other  move.

Voltage This is basically the force that 'pushes' electrons around a circuit...ie gives them energy. A voltmeter measures the difference in energy between.

Measuring Current

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

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

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

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

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

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