A) Potential difference across the terminals of a cell in a closed circuit is always less than its emf.
B) Internal resistance of a cell decrease with the decrease in temperature of the electrolyte.
C) Potential difference versus current graph for a cell is a straight line with a -ve slope.
D) Terminal potential difference of the cell when it is being charged is given as\[V=\varepsilon +Ir\].
