Resistor value is fixed and it will not change.

We know ohms law,V=IR
Here V is changed to 2V
and so current changes from I to 2I
Therefore,2V=2IR
which implies,V=IR
Hence remains the same.

In this question the voltage & current across the resister is double i.e.
2v=2I*resister (R)
2V/2I =R
v/i= R
According to the Ohm's law the value or resister is remain same
2v=2I*resister (R)
2V/2I =R
v/i= R
According to the Ohm's law the value or resister is remain same
