difference between conductor and resistivity
Answers
Answer:
For a conductor, the resistance is directly proportional to the length of the conductor and inversely proportional to the area of cross-section. ... Resistivity is defined as the resistance offered by the material per unit length for unit cross-section.
Answer:
Resistivity is the electrical resistance of a conducting material per unit length. In other words,it is a degree to which a conductor opposes the flow of electricity through itselfr, instead allowing the energy to flow out of the electrical circuit,most often as heat. Resistivity is useful in comparing various materials based upon their ability to conduct electric circuit.
The SI unit of resistance is Ohm.
Conductivity,by contrast,is the degree to which a conductor allows the flow of electricity through itself. The unit of conductivity is the Siemens(S). It was formerly called the mho. Good Conductors retain heat,minimizing the loss of energy from the electric circuit.
