\(m = 0.14\, m^2V^{-1}S^{-1} , n = 1.5 \times 10^{16} \,m^{-3}\)

ચોસલામાંથી પસાર થતો પ્રવાહ \(= I = neV_dA\)

પરંતુ \(w \mu \,\, = \,\,\frac{{{V_d}}}{E}\) \(\,\,{V_d}\,\, = \,\,E\mu \)  

\(\therefore \,\,I\,\, = \,\,neE\mu A\)

અહીં \( V\,\, = \,\,\,E{l}\,\, \Rightarrow \,\,E\,\, = \,\,\frac{V}{{l}}\)

\(\therefore \,\,I\,\, = \,\,\frac{{neV\mu A}}{{l}}\)

\( = \,\,\frac{{1.5 \times {{10}^{16}} \times 1.6 \times {{10}^{ - 19}} \times 0.14 \times 2 \times {{10}^4}}}{{{{10}^{ - 1}}}}\)

\(I\;\, = \,\,6.72 \times {10^{ - 7}}\,\,A\)
