The resistivity is given by-x3C1-mne2-x3C4-where-xA0-n - number density of electrons-x3C1-xA0- relaxation timeWith the-xA0-rise in temperature- number density of electrons and holes -in case of semiconductors- increases- where-xA0-x3C4-xA0-remains constant- So- -x3C1-xA0-resistivity- decreases-

Show on a graph, the variation of resistivity with temperature for a typical semiconductor.

The resistivity is given by:
$ρ = \frac{m}{n e^{2} τ}$
where n = number density of electrons
$ρ$ = relaxation time
With the rise in temperature, number density of electrons and holes (in case of semiconductors) increases, where $τ$ remains constant. So, $ρ$ (resistivity) decreases.

Show on a graph, the variation of resistivity with temperature for a typical semiconductor.

The resistivity is given by:ρ=mne2τwhere n = number density of electronsρ = relaxation timeWith the rise in temperature, number density of electrons and holes (in case of semiconductors) increases, where τremains constant. So, ρ (resistivity) decreases.
