Electrons flow...
|
high to low
|
|
|
Potential difference
|
provides the energy that pushes electrons through the circuit due to electrical force in an electrical field (measured in Volts)
|
|
|
Resistance
|
the slowing down of current flow in a material because of the interaction between the moving electrons and the atoms of wire (measured in Ohms)
|
