Solution:
Firstly we calculate the total current supplied by the battery by determining
the equivalent resistance of the circuit across terminals AB. The total
resistance of the circuit is calculated by successively reducing the circuit as
shown in Fig. 2.140.

The total current supplied by the battery is
Working backwards, the branch currents are calculated. If total current
supplied as calculated is 1.8 A, then current I in Fig. 2.140 (ii) is calculated
