🔋 Battery, Resistors and a Switch: Internal Resistance and Maximum Power Transfer

A 3D bench circuit with a real battery (EMF plus internal resistance), a series resistor, a parallel pair and a switch: solve Kirchhoff's laws, see potential steps and drift, and find the load that draws maximum power.
