Problem 3.183

Find the current flowing through the resistance RR in the circuit shown in Fig. 3.46.3.46 . The internal resistances of the batteries are negligible.

Reveal Answer
I=[E(R2+R3)+E0R3]/[R(R2+R3)+R2R3]I=\left[\mathscr{E}\left(R_{2}+R_{3}\right)+\mathscr{E}_{0} R_{3}\right] /\left[R\left(R_{2}+R_{3}\right)+R_{2} R_{3}\right]
