Find the current produced at room temperature in a pure germanium plate of area 2 xx 10^(-4) m^(2) and of thickness 1.2 xx 10^(-3) m when a potential of 5 V is applied across the faces. Concentration of carries in germanium at room temperature is 1.6 xx 10^(6) per cubic metre. The mobilities of electrons and holes are 0.4 m^(2) V^(-1) s^(-1) and 0.2 m^(2) V^(-1) s^(-1) respectively. The heat energy generated in the plate in 100 second is.

A potential difference of 2V is applied between the opposite faces of a Ge crystal plate of area 1cm^(2) and thickness 0.5 mm. if the concentration of electrons in Ge is 2xx10^(19)//m^(3) and mobilities of electrons and holes are 0.36 (m^(2))/("volt-sec") and 0.14(m^(2))/("volt-sec") respectivity, then the current flowing through the plate will be-

A potential difference of 2V is applied between the opposite faces of a Ge crystal plate of area 1 cm^(2) and thickness 0.5 mm . If the concentration of electrons in Ge is 2xx10^(19)//m^(3) and mobilities of electrons and holes are 0.36(m^(2))/(vol t-sec) and 0.14 (m^(2))/(vol t-sec) respectively, then the current flowing through the plate will be
