    Internal Resistance problem when batteries are connected in opposition

    A simple circuit with 2 batteries and a resistor connected in series. The positive terminals are connected to each other via a 4.5 resistor. Their emfs and internal resistances are below. What is the resultant emf? battery 1: ε=6V r=1Ω battery 2: ε=24V r=0.5Ω resistor connecting...
