It has varied from universe to universe. 

The Post-Crisis Universe had the power being literally shared between Captain Marvel, Captain Mary Marvel and Captain Marvel Jr, and if all three were transformed, they weren't as powerful as they would be if only one was transformed. 

That has not proven to be the case in other universes.
