As the temperature of most conductors increases, the resistance decreases.
Electric charges that are different attract each other.
The electrons in an insulator are tightly bound to their atoms.
The unit of measure for voltage is the ohm.
For a constant voltage, increasing the resistance will cause the current to decrease.
