Here's the setup, the three items below are in series:
Battery at 215V
Power supply at 250V (It is a 5A constant current power supply that will drop voltage down to 200V minimum before failing)
8 ohm resistor
When I flip on the charger, I am pushing 3.5A and reading 35V across the resistor. Shouldn't an 8 ohm resistor put through 4.375A? The voltage across the power supply remains at 250V so I don't think it is limiting the current. Or is it?
I have had this issue before and can't explain it. How can I use Ohm's law to size my resistors in this situation?
