Resistance and conductance are- - - - - - to each other.

A conductor of resistance R and conductance G is stretched to twice its original length keeping its volume constant. Calculate the new resistance and the conductance of the conductor.

Resistivity of a conducting wire :

Two identical cells each of emf epsilon , having negligible internal reistance r, are connercted in parallel with each other across an external resistance R. What is the current through this resistance.

The reciprocal of resistance is conductance. If the unit of resistance is ohm, the unit of conductance will be

At infinite dilution of an electrolyte, the equivalent conductance of cations at anions are ………………… of each other.

A wire of length l , mass m and resistance R slides without any friction down the parallel conducting rails of negligible resistance . The rails are connected to each other at the bottom by a resistanceless rail parallel to the wire so that the wire and the rails form a closed rectangualr conducting loop. The plane of the rails makes an angle theta with the horizontal and a uniform vertical magnetic field of the inducetion B exists throughout the rregion. Find the steady state velocity of the wire.

X and Y are large, parallel conducting plates close to each other. Each face has an area A . X is given a charge Q . Y is without any charge. Points A,B and C are as shown in the figure.
