Methods to Determine Cable Size under Harmonic Condition

In Lab 8, the time constant of resistance-capacitance was measured in order to determine the charge of a capacitor. This experiment was conducted by setting building a circuit that connects the voltmeter across the resistor. The voltmeter was then connected across the capacitor. The above procedure was conducted several times using different voltages. Afterwards, the results were calculated and tabulated. The data obtained from the lab were the theoretical Tau for 5V, 4V and 3V. In this experiment, the calculated voltage was also determined. The theoretical and the calculated values were then compared and evaluated by determining their percentage errors. For example, in the 5V, the theoretical value was 1.23V; calculated value was 1.434 with a percentage error of 16.6 %( for voltmeter across capacitor).

The most profound finding of this experiment is that the inductance of the secondary coil does not influence the overall performance of the system in a real-world scenario. The factor that influenced the real-world performance most is the total resistance/loss in the secondary, which is shown by an inversely proportional relationship. As the effective resistance of the secondary coil decreased, its performance went up, as shown by the trend lines in Graphs 1 and 4.

\emph{Testing Strategy:} The graph between applied load in the range 0.5 grams to 575.5 grams and change in voltage is plotted. The graph obtained (see Figure~\ref{f:olggraph}) shows the inconsistent readings at many points for different combination of force applied. Also, the best curve equation is close to cubic, which is indication of bad design.\\*

Lastly using the theoretical value for the RLC circuit and Equation 2, we calculate a Q-factor of Q=0.19. This low Q-factor indicates that the peak of the curve is not very sharp and there could have been overdamping, which potentially increases the error in reading the resonant frequency, especially for the reading by

Introduction: Voltage can be thought of as the pressure pushing charges along a conductor, while the electrical resistance of a conductor is a measure of how difficult it is to push the charges along. Using the flow analogy, electrical resistance is similar to friction. For water flowing through a pipe, a long narrow pipe provides more resistance to the flow than does a short fat pipe. The same applies for flowing currents: long thin wires provide more resistance than do short thick wires. The resistance (R) of a material depends on its length, cross-sectional area, and the resistivity (the Greek letter rho), a number that depends on the material. The resistivity

Briefly describe the layered construction of a coaxial cable from the inner core to the outer insulation. Use your textbook and Internet research to compose your answer.

2. Try increasing the resistivity of the resistor, ρ. How does this change the “look” of the resistor? Describe how that relates to the formula you just wrote (direct, indirect relationships, etc.). What happens to the value of “R” (Resistance)? Is this something that can be changed in a resistor that you would buy in a store to use in a circuit?

was derived and a relationship between Vinv and Vc was obtained (see Fig. 2). Applying voltage balance

Theoretical analysis is one of the most significant phases of the project. The high resistance measurement system developed during this project is primarily based

Where Zo is the CPE constant, W is the angular frequency (in rad/s), i2 = -1 is the imaginary number and (n) is the CPE exponent. Based on (n), CPE can represent resistance (n = 0, Zo = R),

One of the most common ways to parametrize a circuit is by using the equivalent model of the transistor to the small signal analysis (used for low frequencies), or the S-parameters analysis, especially for RF circuits. However, these tests are only accurate enough for sizing linear devices, which is not the case of power amplifiers. Thus, it is necessary to resort to the analysis of large signals. For large signals, both the output and input impedances have to consider the values of frequency, DC voltage, output power, temperature, input power and

i. Industry testing on STP cable has shown that the addition of a shield does increase the usable bandwidth of the cable by increasing the noise rejection between each of the wire pairs. However, the tests have shown that there is not a significant advantage of placing a shield over a properly installed 4pair 100-ohm UTP cable.

Coaxial cable are classified according to it impedance. The one used in this exercise will use the impedance of 70 ohms with RG-58. This can be used for the discussed high speed internet requirements discussed above.

Throughout this research paper, the reader will have a better understanding of the different forms of resistance. Also the reader will have the ability to compare the two types of resistance which were active and passive. And finally the reader will be abl
