Is A(cross sectional area)* I (current) = V (voltage how?

Expert Answer:

No, that is not possible. It is not dimensionally correct. Please give the complete context which would help us understand the problem better. 
V = IR (as per ohms law)
and R = resistivity*l (length of the material)/A
Hence, V = I*resistivity*l/A
