FM Transmitter Here is the schematic‚ PC board pattern‚ and parts placement for a low powered FM transmitter. The range of the transmitter when running at 9V is about 300 feet. Running it from 12V increases the range to about 400 feet. This transmitter should not be used as a room or telephone bug. Part Total Qty.

Discussion In the experiment AC circuits‚ the purpose was to see the effect that a capacitor‚ resistor‚ and inductor have on the voltage‚ and current of a circuit. We created circuits with 2 resistors‚ a capacitor and a resistor‚ and then a capacitor‚ resistor‚ and an inductor. The circuits were then hooked up to a function generator‚ and oscilloscope to find the voltage across certain frequencies and then calculate the peak current‚ capacitive reactance or the inductive reactance‚ and phase difference

Research Paper – Georg Ohm Georg Ohm was a German physicist born in March of 1789. Georg came from a Protestant family. His father who was a locksmith Johann Wolfgang Ohm‚ and his mother who is Maria Elizabeth Beck‚ was the daughter of a tailor. Even though his parents had not been really educated at the time‚ Ohm’s father was a very wise man who had educated himself and his son Georg. In my research I found out that he wrote an elementary grade geometry book while teaching mathematics at

THE MERITS AND DEMERITS OF HOEY ’S MATCHING PATTERNS By Prof.Dr Lubna Riyadh Abdul Jabbar Abstract Within the realm of the linguistic description of text‚ Hoey has adopted the approach that sees text as possessing organization‚ that is‚ describable in terms of patterns of organization. Accordingly‚ organizational statements of text describe what is done by accounting for probabilities. In such an approach‚ no linguistic combination is impossible‚ but some are decidedly

RC Circuits •In this presentation‚ circuits with multiple batteries‚ resistors and capacitors will be reduced to an equivalent system with a single battery‚ a single resistor‚ and a single capacitor. Kirchoff ’s laws will be stated‚ and used to find the currents in a circuit. In addition‚ the equation for the time-constant of an RC circuit will be derived. Ohm ’s Law When a battery is connected to a resistor‚ the battery will cause a current to flow through the resistor. The larger the voltage

ZEIT 1206 DEC1 Lab Report 1 DC Circuits - Analysis and Design Alexander Glover‚ z3422512 Abstract DC circuit analysis and design‚ play a massive role in electrical engineering and without the correct application of theory and practise in unison‚ nothing can be achieved in a true engineering sense. Engineering requires theory to develop and test constraints while also requiring practical application of theory in order to determine tolerance and practical results for industry purposes.
