According to Ohms law,
V=IR and R=V/I.
If V doubles and it become 2V and I doubles and it become 2I.
Therefore R = 2V/2I = V/I (R values not change).
V=IR and R=V/I.
If V doubles and it become 2V and I doubles and it become 2I.
Therefore R = 2V/2I = V/I (R values not change).

The resistance R is dependent neither on the voltage V nor on the current I. So R will remain constant.

1. The resistance of a conductor is constant under constant temperature and pressure
2. The applied voltage is directly proportional to the current flowing through the conductor.
Hence the resistance value remains constant R = V/I.
2. The applied voltage is directly proportional to the current flowing through the conductor.
Hence the resistance value remains constant R = V/I.
