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