Answer #1

Resistance R is the property of a given resistor.If resistor remains same then its restance R is constant.Moreover, Ohm's law states that Voltage across the given resistor at constant temperatire is directly proportional to the current across it. V = RI ; V and I are the voltage and the current respectively,and R is the constant of proportionality called resistance of the resistor.Here, Resistance being the property of given conductor in the form of the resistor is fixed.
