The Germanium’ is a poem written in free verse by Theodore Reothke which explores the ’frail ’ relationship between the persona and his wife‚ or lover who is personified as a ’ geranium’. written in first person perspective‚The poem shows the compulsive obsessive love the persona feels for this lady who has had a hard life and is now on death’s bed through the usage of flower imagery and symbolism.Themes like loneliness‚ lost love and everyday experiences of mankind have been communicated

Semiconductors: Band Gap of Germanium and the Hall Effect Friday‚ Section 006 TA: Yilikal Ayino John Greavu with Daniel Erickson & Kevin Haar February 14‚ 2014 PreLab With the new understanding of quantum mechanics and solid-state physics in the 1930’s came the development of semiconductors. Semiconductors are materials such as silicon and germanium in which the current density is non-zero‚ unlike an insulator‚ yet still several magnitudes smaller than that of a conductor. There exists a significant

bobby pin could not replace the germanium diode‚ and that the crystal radio ware efficient as a normal store bought radio. On experiment two the crystal radio had like 3 stations. The sound was very clear and loud. Also‚ the bobby pin method did not work. There were lots of hypothesis that did not support the results. Some hypothesis that did not support was that the safety pin could replace the germanium diode. The safety pin wasn’t suitable to replace the germanium diode. One of the rejected hypotheses

Devices‚ Devices‚ Microchips? Many people have a device that they keep important information on. If they should ever lose it and can’t get another one when they need it‚ what would they do? Microchips might be the answer to this problem. Microchips are being improved by a few companies. In the future‚ companies may invest millions to start making microchips. Microchips are already expensive and most companies won’t spend much money to make microchips currently. Intel is one of the few companies

It also does exactly same thing as above except that it has a negative voltage on its collector and a positive voltage on its emitter. [pic] Transistor is a combination of semi-conductor elements allowing a controlled current flow. Germanium and Silicon is the two semi-conductor elements used for making it. There are two types of transistors such as POINT CONTACT and JUNCTION TRANSISTORS. Point contact construction is defective so is now out of use. Junction triode transistors are in

1 IDENTIFICATION OF BASIC ELECTRONIC COMPONETS THEIR CHARACTERISTICS & TESTING 1.0.0 INTRODUCTION An electronic circuit is composed of various types of components. Some of these components are termed as active components because they take part in the transformation of the energy while other components‚ which only dissipate or store energy‚ are called as passive elements. The vacuum tubes‚ rectifier‚ transistors are some of-the common active while the resistances‚ which dissipate the power

electronic applications‚ such as bulk in size‚ slow operating speed etc. Carbon‚ Silicon and Germanium are belonging to the same group in the periodic table. They have four valance electrons in their outer shell. Pure Silicon and Germanium are semiconductors in normal temperature. So in the earlier days they are used widely for the manufacturing of electronic components. But later it is found that Germanium has many disadvantages compared to silicon‚ such as large reverse current‚ less stability towards
