Half its length
Double its width
Double its length
Double its length AND half its width
V=IR, where V=Potential difference, I=current, R=resistance
R=V/I where V=Potential difference, I=current, R=resistance
Current is proportional to Potential difference
A resistor will have a constant resistance at a fixed temperature whatever the current.
A resistor has a constant resistance.
