Resistance between A and C (Fig. ...
= 6 || 3 = 2 Ω
Resistance of branch ACD = 18 + 2 = 20 Ω
Now, there are two parallel paths between points A and D of resistances 20 Ω and 5 Ω.
Hence, resistance between A and D = 20 || 5 = 4 Ω
∴ Resistance between A and B = 4 + 8 = 12 Ω
Total circuit current = 60/12 = 5 A.
