If you pass a metal conductor through a magnetic field an electrical field is generated in that conductor. When you place two cables next to one another EMI will cause cross-talk which is where signals from one cable is picked up on the other cable. Because fiber does not conduct electricity and uses only light signals in a glass fiber instead of electrical signals through a metallic conductor, to transmit data. Since it does not use any metallic media it is immune to EMI. Higher Possible Data Rates (Oliviero 250) are possible because light is immune to interference and can be modulated at very high frequencies.
One of the biggest disadvantages is not being able to make connections as easy as the copper. Fiber optic cables have a core as fine as a human hair, making it extremely difficult to splice. Copper cables are obviously not going to be around forever with the fiber optics being so futuristic, but they still have advantages over the fiber. Copper is very easy to work with. When making connections it is so much easier to splice the copper cable than it would be for the fiber.
As the voltage increases across D5, the frequency of oscillation increases. The stub is just acting like a coil in this circuit, and because it is part of the circuit board layout, it has a very predictable value. This prevents us from having to tune anything in this section like our old products. Just turn the unit on, and you are good to go! The best part of the stub is it’s low sensitivity to microphonics (Microphonics is the noise generated in a VCO (voltagecontrolled oscillator) circuit by vibrating components which change in value slightly because of
Rajeev Pathapati Limiting Reactant Lab Chemistry 6th Due: 2/9/12 Introduction: When a chemical reaction occurs, there is usually a limiting reactant. In a chemical reaction, the limiting reactant, also known as the limiting reagent, is the reactant that is totally consumed at the end of a chemical reaction, and is the reactant that limits the amount of product formed. This also results in excess of the other reactant(s). The reaction tested in this experiment was between a Copper (II) Chloride aqueous solution, and Aluminum metal. The purpose of the lab was to determine which reactant was the limiting reactant, and to see how much of the other reactant was used.
This is just to avoid the hot steel damaging the table. Now turn the fan on and face it towards the block of steel. The fan will cool the steel down. Using the digital thermometer record the temperature of the block of steel every minute. These temperatures are the actual temperature.
Strong electrolytes produce large numbers of ions, which results in high conductivity values. Weak electrolytes result in low conductivity, and non-electrolytes should result in no conductivity. In this experiment, you will observe several factors that determine whether or not a solution conducts, and if so, the relative magnitude of the conductivity. Thus, this simple experiment allows you to learn a great deal about different compounds and their resulting solutions. In each part of the experiment, you will be observing a different property of electrolytes.
Single-Mode Fiber uses a very narrow glass core and can transmit data at very high speeds or long distances. Multi-Mode Fiber uses a thicker glass core than single-mode fiber. As I have discussed each cabling solution has its own advantages and disadvantages. Copper cabling is best
Natural gas also isn’t high in nitrogen oxide or sulfur dioxide. It is more environmentally friendly to extract natural gas than burn coal. Hydraulic fracturing is the use of fluid and material to create or restore small fractures in a formation in order to stimulate production from new and existing oil and gas wells. This creates paths that increase
Copper Cycle Lab Purpose: In this experiment the student will gain familiarity with basic lab procedures, some chemistry of a typical transition element, and the concept of percent yield. Equipment: Balance (2) 250 mL beakers Evaporating dish Stirring rod Hotplate 100 mL grad cylinder Weighing paper Materials: 0.5 g of copper wire 2.0 M H2SO4 (aq) Acetone Conc. HNO3 (aq) 3.0 M NaOH Granular zinc Introduction: Understanding the type of reaction taking place is an important part of predicting the products of a reaction. Common chemical reactions can be described as synthesis, decomposition, single replacement, double replacement, combustion, or oxidation and reduction reactions. Each of these types of reactions behaves in a similar fashion.
The standardization of of KMnO4 solution with Na2C2O4 is as follows: Oxidation: Na2C2O4→2Na++2CO2+2e- Reduction: KMnO4+8H++5e-→K++Mn+2+4H2O And the overall balanced equation: 16H++5Na2C2O4+ 2KMnO4→10Na++2CO2 These reactions are thermodynamically spontaneous, but the final one is susceptible to a side reaction and it is naturally very kinetically slow (Blandamer et al. 1998). The MnO2 present in the reaction in KMnO4 must be filtered to remove it because it interferes with the
