A battery of emf E has an internal resistance 'r'. A variable resistance R is connected to the terminals of the battery. A current I is drawn from the battery. V is the terminal P.D. If R alone is gradually reduced to zero, which of the folowing best describes I and V ?

A

`I` approaches infinity,`V` approaches `E`

B

`I` approaches `E//r`, `V` approaches `E`

C

`I` approaches `E//r`, `V approaches zero

D

`I` approaches zero,`V` approaches `E`.
