By increasing the temperature , the specific of a conductor and a semiconductorA. increases for bothB. decrases for bothC. increases, decreasesD. decreases , increases

Answer» Correct Answer - C
Specific resistance is resistively which is given by
`p = (m)/(ne^(2) tau) `
where `n = no` , of free electron per unit valume
and `tau = `average relacation time
for a conducter with rise in temperatute and `tau `decreases But decreases in `tau` is more dominant than increase in `n` resulting an increase in the value of p
for a semiconducter with rise in temperatute and `tau `increases and `tau` decreases but the increases i `n` more dominant than decrease in `tau` resulting an decrease is the value of p
