0For a cell, the terminal potential difference is \( 2.2 \mathrm{~V} \)
\( \mathrm{P} \) when circuit is open which reduces to \( 1.8 \mathrm{~V} \) when
W it is connected to a resistance of \( \mathrm{R}=5 \Omega \); then internal resistance of the cell is :-
(1) \( \frac{10}{9} \Omega \)
(2) \( \frac{9}{10} \Omega \)
(3) \( \frac{11}{9} \Omega \)
(4) \( \frac{5}{9} \Omega \)
