A student measures the terminal potential difference (V) of a cell ( of emf E and internal resistance r) as a function of the current (I) flowing through it. The slope and intercept of the graph between V and I, then respectively equal to

A set of 'n' equal resistors are connected in series to a battery of emf 'E' and internal resistance 'R'. The current drawn is I. Now of value 'R' each the 'n' resistors are connected in parallel to the same battery. Then the current drawn from battery becomes 10I. The value of 'n' is?
