The Maharaja of Pratibandapuram is the Tiger King. He got that name because at the time of his birth, astrologers predicted that he would die due to a tiger. So when he grew up, he decided to kill all the tigers and came to be known as the Tiger King. He killed ninety-nine tigers but the hundredth tiger, a wooden one, was instrumental in his death.

Resistance increases, in case of conductor, with increase in temperature and decreases, in case of insulator, due to increase in temperature.

 

In case of conductor, the valance band and conduction band overlap with each other. So, there are excess electrons in the conduction band of a conductor. When you increase the temperature, more electrons will go to the conduction band from valance band by absorbing the energy. So, the conduction band becomes crowded and there will be more collision between the electrons which increases the resistance. So, with increase in temperature, the resistance of conductor increases.

 

But in case of insulator, there is a large energy gap between the two bands. So, if the temperature rise is high, the electrons will go to the upper band. But since it is not crowded due to less number of electrons, so the conductance will increase due to availability of free electrons in the conduction band. So, the resistance decreases with increase in temperature in insulator.

 Electric potential difference between two points in an Electric field is defined as the amount of work done in moving unit positive charge from one point to another point against the electric force.

In other words, Potential difference is simply the difference of scalar potentials between two points or anything you consider.
