Is A(cross sectional area)* I (current) = V (voltage how?
Asked by Shivansh Arora | 28 Jun, 2013, 02:27: PM
answered-by-expert 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
