is the change in the collector current in the transistor whose base current changes by Q. 5. Name the underlying principle of the working of an optical fibre. 1 1 Q. 6. Define ‘dielectric constant’ of a medium. Briefly explain why the capacitance of a parallel plate capacitor increases‚ oii introducing a dielectric medium between the plates. 2 Q. 7. Why does a paramagnetic substance display greater magnetisation for the same magnetising field when cooled? How does a diamagnetic substance respond

Introduction Many researchers‚ scientists‚ and environmentalists are expressing concerns about changes in the overall climate of the earth. Some believe that a dramatically dangerous warming is taking place in the overall global climate‚ a problem that is referred to as "global warming." This paper will attempt to explore this very issue‚ its causes‚ dangerous and somehow deadly effects and how we could deal with this global crisis. Global warming has become perhaps the most complicated issue

are connected to the external electrical circuit that provides a constant bias voltage between the droplet and the electrode. External mechanical actuation is used to move the droplet in such a way as to force a decrease of its overlap with the dielectric-film-coated electrode. This results in the decrease of the total charge that can be maintained at the droplet liquid – solid interface. The excessive electrical charge then flows back through the electrical circuit that connects the droplet and

And he did a remarkable work on his major project of designing a working model of 7 GHz (C band microwave) Dielectric Resonator oscillator. He has been an above average student all his life which is also well supported by his academic scores. I can stand guarantee for his aptitude and information in the field of embedded systems mentioned subjects. I strongly
