The reference polarity for the voltage \\( v=12 \\mathrm{~V} \\) and the current direction \\( i \\) are as shown for two car batteries \\( A \\) and \\( B \\). If the current is measured as \\( i=-50 \\mathrm{~A} \\), (a) explain the reasoning allowing you to determine which car has the dead battery anc (b) determine the energy transferred if this current is maintained for \\( 2 \\mathrm{~min} \\).
