Question

obtain an expression for specific resistance give its SI units​

Answer 1

Answer:

V=IR,SI unit is Ohm

Explanation:

If the physical state of a conductor remains constant, the current (I) following through it is directly proportional to the potential difference (V) between its two ends.

I alpha V

I=kV (k is the constant of proportionality)

I×R=V

Hence, V=IR

Or R=V/I
