circuit EMF 2V, has a rheostat and wire in series. The wire is 3.4 ohms, and rheostat goes from 0-1500ohms
Asks to calculate the maximum and minimum p.d. that the wire can have.
I understand that maximum p.d. is 2, but i figured minimum would be 3.4/1503.4, however the MS says that it has to be 2x(3.4/1503.4). Why does it have to be doubled?
