For an electrical conductor, by Ohm`s law:

If V = Voltage across its ends ,

R= resistance offered to current flow

and I = Current flowing through it , then

1. V is directly proportional to I.

2. The ratio V/I is constant and equal to R.

If V = Voltage across its ends ,

R= resistance offered to current flow

and I = Current flowing through it , then

1. V is directly proportional to I.

2. The ratio V/I is constant and equal to R.
