The two ends of a uniform conductor are joined to a cell of e.m.f. E and some internal resistance. Starting from the midpoint P of the conductor, we move in the direction of current and return to P. The potential V at every point on the path is plotted against the distance covered (x). which of the following graphs best represent the resulting curve ?

First a set of n equal resistors of R each are connected in series to a battery of emf E and internal resistance R. A current I is observed to flow. Then ,
the n resistors are connected in parallel to the same battery. It is observed that the current is increased 10 times. What is 'n'? ,
