50C. Electrons must flow from b to a to increase the energy in the battery.

#### Work Step by Step

$600J\div12V=50C$ Positive current flow must occur from terminal a to terminal b to increase the energy stored in the battery, as the passive reference is a to b. In this case, electrons would create negative current flow, so the electrons must flow opposite of the positive current.
