Resistor resists current it means it opposes the current flow while a conductor conducts current it means it allows the current flow without any interruption. So these are always inverse to each other.

When resistor is increased then conductor decreases, resistor is always get high advantage more than conductivity. Thats for its inversely proportional to conductivity.

Acc.to ohm's law current flowing through the conductor is directly proportional voltage & inversely proportional to resistance temperature remain constant.

As conductivity is inversely proportional to resistivity and we know that resistance is directly proportional to resistivity.
So R=1/s.
So R=1/s.

When the resistance goes to negligible level then only the material act as conductor. So both are inversely proportional to each other.

Resistive is limiting the current while conductive is passing the current hence they are inversely proportional.

When the short circuit occur, resistances in the circuit decrees, and the conductivity increases. Hence R=1/s

Resistance and conductance are inversely proportional to each other. Hence it gives the relation stated above.

Here resistance is inversely propotional to current ie if resistance inc the current passing will decrease.

Because conductivity is a reciprocal of resistivity.and its unit is also inverted.unit is "mho".
