Electrostatic Essay

The cause of static electricity is when there is an unbalanced molecular construction or non conductive insulators such as plastic, glass, ceramics, and other non conductive materials

Two everyday life situations where we experience static eletricity are walking on a carpet with socks which is due to friction and rubbing your hands together which is due to charging by induction.

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).

When the objects rub together electrons can move to the other object. Charging by conduction is the transfer of electrons by direct contact. Charging by induction is the movement of electrons to one part of an object that is caused by the electric field and second object.

When combing your hair, you scuff electrons from your hair onto the comb. Is your hair then positively or negatively charged? How about the comb?

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

20. Because the magnetic force which deflects the electrons is defined by F = q * v x B

Where α is an empirical parameter (0 ≤α≤1) and f is the frequency in Hz. This formula considered the deviation from the ideal RC-behavior due to surface inhomogeneties, roughness effects, and different compositions of surface layers 40, 41. The first time constant at low frequency range was claimed to the presence of an inhomogeneous passive film 42. A constant phase element (CPE) was used instead of a pure capacitance due to these inhomogenities, which were found at the oxide/electrolyte interface and under the oxide film. CEE can be introduced in terms of impedance from the following equation:

The Railroad and the Pony Express has been the only way to communicate remotely and send correspondence. Joseph Henry and Samuel F.B. Morse would sculpture the future of communication with the invention of the electromagnet and telegraph. Joseph was a graduate of Princeton (Then called the College of New Jersey) as a physicist. The fascination with electricity and magnetism in which he had read reports on from Europe fascinated his desire to research and develop an electromagnet. This shaped our future of electricity as we see it today. With the ability to distinguish between high amperage circuits and high voltage circuits, this laid the baseline for what we know today as “Inductance”. Electrical conductor produces energy by the changing of current or the changing of voltage to produce a strong magnetic force while only using a small battery. By Joseph Henry’s introduction to inductance also paved a path for the invention of electric motors. These advances in technology developed a method for illuminating homes and streets. The use of electricity was spreading almost as fast as the railroad. This improved the lifestyle and functionality of America. (Tindall, Shi

Task Description:The world communicates by making extensive use of the electromagnetic spectrum. For the average person this is commonly accessed using radio waves. These radio waves may be over the AM or FM radio wave bands or the radio waves that transmit our television signals. Not only are people always within a ‘phone call of each other anywhere in the world they are also able to find out exactly where in the world they are by use of

Originally electricity and magnetism were thought of as two separate forces. This view changed, however, with the publication of James Clerk Maxwell's 1873Treatise on Electricity and Magnetism in which the interactions of positive and negative charges were shown to be regulated by one force. There are four main effects resulting from these interactions, all of which have been clearly demonstrated by experiments:

Explains the effects of the temperature, impurities, and deformation on Electrical Conductivity in which the Drude Model

There are three main sections to this module: terrestrial coordinates, celestial equatorial coordinates, and understanding how the ecliptic is related to seasons on the Earth. Each of these sections has its own simulator(s). The background material necessary to utilize these tools is contained in each section.

Now we will move onto other materials that are involved with electronics. The next group of materials that will be discussed are insulators. An insulator is a material that does not conduct electricity at all but will resist or stop it from traveling further. An insulating atom has eight electrons in its valance shell which makes this shell complete. Eight is the most electrons that any atoms can have in their valance shell this is why these are called insulators, no more electrons can fit in the valance shell of these atoms.
