Hi Joseph,

Although they are in fact the same circuit, everything you need to know for each question is told to you in each question.

The voltage supply is indicated by the notation on either end of the circuit diagram. We’ve mentioned that at least a couple of times in previous videos – look at it again and see if the notation rings a bell. If not, let me know!
