Two cells \( A \) and \( B \) of EMF \( 1.3 \mathrm{~V} \) and \( 1.5 \mathrm{~V} \) respectively are arranged as shown in figure-3.322. The voltmeter connected in
\( \mathrm{P} \) circuit is ideal and it reads \( 1.45 \mathrm{~V} \). Which cell has the higher internal resistance and how many times that of the other?
