In Fig. 4.32 epsilon(1) " and " epsilon(...

In Fig. 4.32 `epsilon_(1) " and " epsilon_(2)` are respectively 2.0 V and 4.0 V the resistances `r_(1),r_(2)` and R are respectively `1.0 Omega, 2.0 Omega " and " 5.0 Omega`. Calculate the current in the circuit. Also calculate (i) potential difference between the points b and a, (ii) potential difference between a and c.
