0In a circuit shown in Fig. \( 3.54 \) resistances \( R_{1} \) and \( R_{2} \) are known, as well as emf's \( \mathscr{E}_{1} \) and \( \mathscr{E}_{2} \). The internal resistances of the sources are negligible. At what value of the resistance \( R \) will the thermal power generated in it be the highest? What is it equal to?
