Hey
Potential Difference given is : 2V
Resistance is : 2 ohms
By Ohm's Law, one can easily utilize the relation :
[tex]v = ir[/tex]
Where, { v , i , r } are the potential difference, current and Resistance Respectively.
Hence,
[tex]i = \frac{v}{r} = \frac{2}{2} = 1a[/tex]
Hence, the Current is 1 Ampere
