The Big 3 Current (Amps) Resistance and Impedance (Ohms) Potential Difference (Volts)
6
A peculiar way of thinking? Current as electron vibration
7
A peculiar way of thinking? Resistance: transfer of electron energy to atoms resulting in energy dissipation by heating.
8
A peculiar way of thinking? Electrical Potential = energy possessed by electrons Potential Difference = energy transferred from electrons to a component
