Understanding the basics §

Current §

Some comment

power is energy rate (Joules per unit time), current is charge rate (electrons per unit time), and voltage is energy per unit charge (Joules per electron). Voltage makes a lot more sense as the excitation of electrons; them wanting to jump gaps and go to a lower energy place feels more intuitive in that framing.
