Basic Electrical Engineering - 3. RESISTANCE & RESISTIVITY || NUMERICAL || Explained in Nepali

One of the major difference between the resistance and the resistivity of the material is that the resistance opposes the flow of free electrons whereas the resistivity is the property of the material which defines the resistance of the material having specific dimension. The resistance is the property of the material which creates an obstruction in the flow of the current. When the voltage is applied across the conductor, the free electrons starts moving in a particular direction. While moving these electrons collapse with atoms or molecules and hence produce heat. These atoms or molecules oppose the movement of free electrons in a material. The resistivity is also known as specific resistance. The resistivity represents the resistance of the material which has specific dimensions, i.e., the material has 1-meter length and 1 square meter area of cross section. ......................................................................................................................
