A) resistivity
B) conductivity
C) potential difference
D) resistance
Correct Answer: A
Solution :
\[B=\frac{C}{A}=\frac{E}{h}=\frac{E}{i/A}=\frac{EA}{i}=\frac{EA}{n\,\,e\,\,A\,\,{{v}_{d}}}\] \[=\frac{E}{n\,\,e\,\,(e\,\,E\,\,\tau /m)}=\frac{m}{n\,\,{{e}^{2}}\tau }=\rho \]You need to login to perform this action.
