- There are only silicon controlled rectifiers and not germanium because
- Si is available as compared to Ge.
- Only Si has stable off-state.
- Ge is very temperature sensitive.
- Si only has the characteristic a1 + a2 < 1 at low collector currents and reaches 1 at high currents.
Homework Answers
Answer is c
Silicon crystals are less sensitive to temperature, ( High ability to withstand at high temperature.) Since SCRs are used in High Power devices.

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
