Q. A Si and a Ge diode has identical physical dimensions. The band gap in Si is larger than that in Ge. An identical reverse bias is applied across the diodes
A) The reverse current in Ge is larger than that in Si
B) The reverse current in Si is larger than that in Ge
C) The reverse current is identical in the two diodes
D) The relative magnitude of the reverse currents cannot be determined from the given data only
Explanation
(c) The reverse current is identical in two diodes if the identical reverse bias is applied across the diodes.
