A battery of emf E and internal resistance r is connected across a resistance R. Resistance R can be adjusted to any value greater then or equla to zero. A graph is plotted between the current passing through the resistance (I) and potential (V) across it. Select the correct alternatives.

Internal resistance of the battery is `5 Omega`

emf of the battery is 10 V

maximum crrent which can be taken form the battery is 2 A

V-I graph can never be a stright line as shown in figure.
