1.	10.A potential difference of V volt is applied across the faces of a germanium crystal plate. The face area of the crystal is A and its thickness is l. The free electron concentration in germanium is n and the electron and holes mobilities are a and b respectively. Then prove that current across the plate will be i = [eAVn(a+b)]/l
