Yes and no. When you draw more current than rated three things can
happen.

1. The supply goes over current until something burns up
2. The supply shuts down electronically (the voltage goes to nil)
3. The voltage diminishes slowly as resistive losses in the supply
use a higher and higher percentage of the voltage drop.

In any case the supply limits the current by limiting the voltage at
the output.

IOW -- the current *is* determined by the supply. :-)

Wrong - the current is LIMITED by the supply. If the supply
can supply the needed current, a bigger supply at the same voltage
will NOT increase the current.
