Ge and Si fiodes start confucting at 0.3V and 0.7V respectively . In the following figure if Ge diode connections are reversed, the value of V changes by: (assume that the Ge diode has large breakdown voltage)
hi,
see actually it is difficult to explain or understand the situation if the figure is not available. I think if you use the formula of kirchoffs voltage law and than the problem can be solved. you may find tata mac graw physics books there is lot of this type of numerical problems is given.
