Finding DC Supply Total Current, Resistance & Voltage

[Cbray]

1) How do i Determine the total current provided by a DC supply?
2) Total Effective Resistance
3) Total Voltage

Asking these questions for a friend, thanks!

the questions as stated are not meaningful with no context except for the 3rd one which doesn't quite make sense. The "Total Voltage" of a, say, 10volt DC power supply is 10 volts. Why would it be otherwise?

Sorry about the small amount of information, I might grab some more information from him later, thanks!
