Question

Which one is the correct diagram for Resistivity vs Temperature for Metals ?

Open in App

Solution

Figure 1 is the correct diagram.
In the materials like metals have lots of free electrons for conduction. Hence this materials can conduct current easily, so they possess less resistance or they are least resisting. Metals offer more electrical resistance with increase in temperature. Hence, the Resistivity of metals highly depends on their temperature and it increases with increase in temperature.
