HI !
Ohm's law states that , at a constant temperature , the potential difference across two ends of a current carrying conductor , is directly proportional to the amount of current flowing through it .
i.e ,
V ∝ I
I ∝ V
V = IR
---------------------------------------------------------------------
potential difference = V = 0.8 v
Current = I = 0.2 A
Resistance = R
V = IR
R = V/I
= 0.8/0.2
= 4 Ω
Resistance of the conductor is 4 Ω
