## Total voltage vs Battery voltage within Circuits

1. The problem statement, all variables and given/known data

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.

2. Relevant equations
I=V/R

3. 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?
