Teaching HTET PGT Level 3 - 2024 Mock Test Physics Current, Resistance and Electricity Drift of Electrons and the Origin of Resistivity
The Einstein relationship between diffusion current “D”and mobility “µ” for an electron is:
1
\(\rm \frac{D}{\mu}=\frac{e}{K_B T}\), Where KBT is the Boltzman’s constant and Tis the temperature
2
\(\rm \frac{D}{\mu}=\frac{2K_B T}{e}\), where KBT is the Boltzman’s constant and Tis the temperature
3
\(\rm \frac{D}{\mu}=\frac{K_B T}{e}\), Where KBT is the Boltzman’s constant and Tis the temperature
4
\(\rm \frac{D}{\mu}=K_BT\), Where KBT is the Boltzman’s constant and Tis the temperature
