the question asks me to draw a graph of electric potential vs distance starting from from point g (starting at g and going around in a clockwise manner).

i am not sure how to proceed. i mean i know voltage is only meaningful if it is measured as a difference between two points. for instance, i know the voltage across the 10 ohm resistor is 0.09009V, which is the voltage at b relative to a. On the graph would i just have b = 0.09009V? If i start at g, does it mean that g has a voltage of zero?

Thanks.

sorry.. about the copying and pasting thing. just click on the link and it should work.

That didn't work either ("forbidden"). Maybe it'll work for other people.
