Explanation:
parallel resistance are 3 and 1.5
1/ R = 1/3 + 1/1.5
= 5+10/ 15
=15/15
R = 1 Omega
now 1 Omega and 4 Omega are in series
R' = 1+ 4= 5 omega
total voltage in a circuit ( V )= total current x total resistance
= 0.3 x 5 = 1.5 volt
current through 3 Omega resistor
V = I x 3
1.5 / 3 = I
I = 0.5 A
