Total: 90
Ge and Si diodes start conducting at 0.3 V and 0.7 V respectively. In the following figure if Ge diode connection are reversed, the value of
V
0
changes by : (assume that the Ge diode has large breakdown voltage)
0.6 V
0.8 V
0.4 V
0.2 V
Validate
Solution:
Initially Ge & Si are both forward biased socurrent will effectively pass through Ge diodewith a drop of 0.3 V
if "Ge" is reversed then current will flow through"Si" diode hence an effective drop of (0.7 – 0.3)= 0.4 V is observed.
