A potential of 5 V is applied across the faces of a pure germanium plate of area $2 \times 10^{-4} \mathrm{~m}^2$ and of thickness $1.2 \times 10^{-3} \mathrm{~m}$. Concentration of carriers in germanium at room temperature is $1.6 \times 10^6 \mathrm{~m}^{-3}$, Mobility of electrons and holes are $0.4 \mathrm{~m}^2 \mathrm{~V}^{-1} \mathrm{~s}^{-1}$ and $0.2 \mathrm{~m}^2 \mathrm{~V}^{-1} \mathrm{~s}^{-1}$ respectively. The current produced in germanium plate at room temperature, is
