Not sure if you're following.
Power flows from high voltage to low. If we were discussing water, it's like having a well pump and water storage tank; and the well pump can supply up to 10 gallons per minute at 14.5 psi. Until the water tank is full, some of those possible 10 gal/min will go to filling the tank. If someone is taking a shower and another is washing dishes there might not be enough flow to do all three things at 14.5 psi.
