For the circuit shown in Figure P31.53, calculate 

(a) the magnitude and direction of the current 

(b) the potential differences \(V_{\mathrm{ab}}, V_{\mathrm{bc}}, V_{\mathrm{cd}}\), and \(V_{\mathrm{da}}\). Use these values: \(R_{1}=4.0 \Omega, R_{2}=2.0 \Omega, R_{3}=6.0 \Omega, \mathscr{E}_{1}=4 \mathrm{~V}\), and \(\mathscr{E}_{2}=8 \mathrm{~V}\).
