    1493 words - 6 pages

    Silicon is the raw material most often used in integrated circuit (IC) fabrication. It is the second most abundant substance on the earth. It is extracted from rocks and common beach sand and put through an exhaustive purification process. In this form, silicon is the purist industrial substance that man produces, with impurities comprising less than one part in a billion. That is the equivalent of one tennis ball in a string of golf balls stretching from the earth to the moon. Semiconductors are usually materials which have energy-band gaps smaller than 2eV.

    The Origin Of Perception

    How do we perceive truth? Where do our personal perceptions of "moral" and "immoral" come from? In this essay I will attempt, using the 8-circuit model of consciousness presented by Dr. Timothy Leary (as interpreted by Robert Anton Wilson in his book "Prometheus Rising") as a template to give one possible way of understanding how we develop into the people we are, and how many use the same process in order to imprint NEW "truths" on others. The first four circuits in Dr. Leary’s model of consciousness are the base for most people's perceptions of reality depending on which they are dispose

    Win At Monopoly

    358 words - 2 pages

    The game of Monopoly was developed by Charles Darrow, who sold it to Parker Bros. in 1935. It is a game where you need luck, strategy and people skills. Understanding and applying these components can increase your chances of winning. The first component of the game is luck. You are controlled by the roll of the dice. After the luck of the dice you must then have strategy. The most important strategy as you start the hame is to buy every property you land on. The exception to this strategy are the utlitiy properties. The utlities are small time and not worth the investment. As you acc

    The main purpose of Lab 1 was to familiarize the students with the equipment within the lab. This was done by taking measurements from multiple circuit setups. The instruments used within this lab include a digital multi-meter, an oscilloscope, and an ammeter. The first section of the lab was to measure the resistance in 10 different resistors to determine if they all fell within the 5% tolerance they are guaranteed. Three of the resistors measured were required to be 4.7k and 3.3k resistance because they were to be used later on in the lab. The other 7 resistors were chosen at random. Table

    ENTPs value their ability to use imagination and innovation to deal with problems. Trusting in their ingenuity to get them out of trouble, they often neglect to prepare sufficiently for any given situation. This characteristic, combined with their tendency to underestimate the time needed to complete a project, may cause the ENTP to become over-extended, and to work frequently beyond expected time limits. Complicating this situation is their predisposition to experiment with new solutions. This makes them eager to move on to the next challenge when things get boring. ENTPs become stressed when

    Q of a Resonant Circuit Experiment 1.10 Abstract Experiment to determine Q of an LCR circuit using 2 methods. Basic LCR setup: L = 31μH, C = 680 pF and R = 3kΩ. The first method is plotting ln Vm against Peak No. and returned Q as 5x10-13. The second method used a capacitor of about ¼ pF to create a weak capacitive coupling and the plot of V0 /Vi gives Q = 2.5. The second experimental method returned the best result. Introduction The aim of this experiment is to measure the quality factor Q of a parallel LCR circuit. This will be achieved by two methods. Simple har

    Ohm's Law defines the relationships between (P) power, (E) voltage, (I) current, and (R) resistance. One ohm is the resistance value through which one volt will maintain a current of one ampere. Ohm's law states that the current through a conductor between two points is proportional to the potential difference and inversely proportional to the resistance. ( I ) Current is what flows on a wire or conductor like water flowing down a river. Current flows from negative to positive on the surface of a conductor. Current is measured in (A) amperes or amps.

    An RLC circuit (or LCR circuit) is an electrical circuit consisting of aresistor, an inductor, and a capacitor, connected in series or in parallel. The RLC part of the name is due to those letters being the usual electrical symbols for resistance, inductance and capacitance respectively. The circuit forms a harmonic oscillator for current and will resonate in just the same way as an LC circuit will. The difference that the presence of the resistor makes is that any oscillation induced in the circuit will die away over time if it not kept going by a source. This effect of the resistor is called

Therefore to power these devices the AC mains must be converted to DC and the voltage must be stepped down as the rated 230V of the mains will damage most digital circuitry.
