WHAT DO YOU MEAN BY RESISTANCE AND RESISTIVITY ???

Asked by  | 11th Apr, 2012, 05:21: PM

Expert Answer:

Resistance is the opposition offered to the flow of current. The more the resistance, the more difficult is for current to flow. Resistivity is defined as the resistance of single unit length of the object with unit area. Resistivity is the property of an object, whereas resistance also depends on length and other dimensions of the object. Resistance can change if the dimensions of the material changes but resistivity will remain the same for a particular material.
