In Figure P31.72, \(\mathscr{E}_{1}=5.0 \mathrm{~V}, \mathscr{E}_{2}=5.0 \mathrm{~V}, \mathscr{E}_{3}=1.5 \mathrm{~V}\), \(R_{1}=50 \Omega, R_{2}=50 \Omega\), and \(R_{3}=50 \Omega\). What are (a) the current in each branch of the circuit and \((b)\) the potential differences \(V_{\mathrm{ab}}, V_{\mathrm{bc}}, V_{\mathrm{cd}}, V_{\mathrm{dc}}, V_{\mathrm{cf}}\), and \(V_{\mathrm{fa}}\) ?
