Question: N sources of current with different emf's are connected as shown in Fig. 3.40. The emf's of the sources are proportional to their internal resistances,

N sources of current with different emf's are connected as shown in Fig. 3.40.
The emf's of the sources are proportional to their internal resistances, i.e. ε = aR, where a is an assigned constant. The lead wire resistance is negligible.
Find:
(a) The current in the circuit;
(b) The potential difference between points A and B dividing the circuit in n and N- n links.
