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 ?

Options

A. I approaches `E//r`, V approaches zero
B. I approaches zero, V approaches E
C. I approaches infinity, V approaches zero
D. I approaches `E//r`, V approaches E

Answer
