The Big 3Current (Amps)Resistance and Impedance (Ohms)Potential Difference (Volts)
A peculiar way of thinking?Current as electron vibration
A peculiar way of thinking?Resistance: transfer of electron energy to atoms resulting in energy dissipation by heating.
A peculiar way of thinking?Electrical Potential = energy possessed by electronsPotential Difference = energy transferred from electrons to a component
V = IR
Battery / Cell provides Potential Difference for circuitBattery/Cell source of Direct Current (DC).
