Battery systems tend to have a terminal voltage that does not decline rapidly until nearly exhausted.
Because the cathode does not change properties during discharge, terminal voltage is quite stable until the cell approaches exhaustion.
Since the permanent magnet field is constant, the terminal voltage varies directly with the speed of the generator.
The terminal voltage across an operating lamp varies depending on the arc current, tube diameter, temperature, and fill gas.
This changes the nature of the relationship between terminal voltages and current.
It was rated at 300 hp and had a terminal voltage of 55 volts.
When an arc starts, its terminal voltage is much less than a glow discharge, and current is higher.
So the proper way to charge a lithium-ion battery is to charge it to a terminal voltage and then stop all charging.
To keep the correct terminal voltage, the magnetic field from the field winding has to increase a lot at large loads.
The terminal voltage of the generators is 15.75kV.
