Compare the voltage at the terminals, as well as the power released in the
external circuit by a battery of 50 cells connected in series and each having a
resistance of 0.2 ohms and an EMF of 2 V, if the external circuit resistance is
0.2 ohms, and an electrophoretic machine that creates a potential difference
of 100 kV on ball conductors and has an internal resistance of 108 ohms, if with
an external circuit resistance of 105 ohms. How will the current and power in
the external circuit change if its resistance doubles?
