Cut-off, is 6.0 V

I don't quite understand what this question is asking in (b) and (d):
What is the difference between total electrical potential and potential provided by the battery?

It sounds like I'm being asked the same question here and I don't see how I would go about solving for voltage total and voltage from the battery.

Homework Equations


I=V/R

The Attempt at a Solution


I found current through the parallel portion of the circuit.

Then, I used that to find the voltage of the entire circuit.

Would that be total voltage, or battery voltage?
