Hi,

Since the resistance branch of 6 and 3 and 12 and 3 are in parallel, so the voltage across each is same.

Hence, the current in the lower branch is I = V/R = 4/15 A

Hence, the potential difference across 12 ohm resistor is

begin mathsize 14px style straight V subscript 12 equals IR equals 4 over 15 cross times 12 equals 48 over 15 equals 16 over 5 equals 3.2 space straight V end style
