Contrarily, when the circuit is opened, the connection is broken and current ceases to flow within the loop. The capacitor then begins loosing its charge and eventually becomes discharged over time. The amount of charge stored by a capacitor however is determined by the length of time for passing the current and the amount of charge being transferred across the loop. This paper will demonstrate the process of charging and discharging a capacitor using an AC, I, current over a period of time, T. the amount of charge acquired by the capacitor, Q is measured and the capacitor allowed to freely discharge over some time. The paper will as well look at the general factors which affect the amount of charge that is stored by a capacitor over a length of time. This will be done by answering certain specific questions of inquiry commonly encountered during a laboratory research experiment. The voltage, V, across the capacitor over time during charging and discharging can be given by the following equation; Q= CV, V is therefore given by the equation V= Q/C. However, Q (t) = Q (I) while the capacitor is charging or discharging. We can therefore use the three equations to derive the equation for obtaining the amount of voltage flowing across the circuit over a period of time, t, by combining the two equations. ...
This is because the time constant is the gradient of the graph obtained after plotting the values of Q against t/RC. This constant (gradient of the graph can be obtained at any point without necessarily projecting the graph to point 0) hence the constant of time during charging and discharging processes. However, the experiment has a lot of flaws hindering the acquisition of accurate measurements of both the voltage stored in the capacitors during charging and that lost during the discharge processes as well as the capacitance of the resistors. These flaws often act as the sources of errors in such experiments. The flow of current within the circuit is often affected by several factors varying from the material composition of the wires used in connection and the length of the same. To begin with, the length of the wires used in connection can affect the flow of current through the connection circuit by increasing the distance over which current flows. These often increases the resistance to the flow of current due to the realignment of the dipoles to enable current flow. The length L of the connection wire is therefore a great source of errors in the flow of current (Bird). Moreover, the transmission of the current across the loop is as well is abject to external environmental interferences such as the changes in temperature t over time as the current is transmitted across the loop. This is because of the occurrence in the internal resistance of the wires which keeps on increasing over time as the current flows. The increase in temperature often lowers the flow of current within the loop, hence a reduction in the amount of voltage stored by the capacitor per unit time and increases the resistance per unit time. Resistors used in almost every electrical Read More

...?Lidia M. Lujan Lab report W14s1 Debate on Global Warming: Scientific Basis Global warming refers to the increase in the temperature of the earth's surface and troposphere. The term global warming is used interchangeably with “climate change,” referring to the other climatic changes aside from or due to increased global temperatures. The change in temperature is attributed directly due to increased in emission of greenhouse gases, largest concentration of which is carbon dioxide. The increased emission arises from human activities in the transport and energy sector (US Environmental Protection Agency). Other human activities like clearing of land, deforestation, and desertification that abet temperature...

...Running head: RECYCLING ALUMINUM TO ALUM Recycling Of Used Aluminum Cans to Alum: A Study Affiliation Introduction Aluminum and its alloys find several applications today, right from soda cans to aircraft material. This is because aluminum is versatile and has many desirable properties: light weight, nontoxic, pleasing appearance, ability to take high polish, high electric and thermal conductivities, corrosion resistance, malleability, ductility, non-magnetic, and non-sparking. (Greenwood & Earnshaw, 1997) Aluminum combines with other metals to give alloys with high mechanical and tensile strengths. The abundance of its ore makes aluminum and its alloys easily available - Aluminum comprises 8.3% by weight of the earth’s crust... head:...

Balance the meter stick in one of the clamps to determine its center of gravity. Place a clamp on one end of the stick to carry a 100-gram weight and slide the stick through the supporting clamp to locate the balance (position of the axis of rotation). Then place another clamp with a 200-g suspension and repeat the same previous step. Record positions with respect...

The niche of an organism is the overall interactions of an organism with other organisms and its range of needs (Properties of microbes). 2. Organisms might compete for food, light, and space. 3. Evolution is the process of gradual development of organisms from simple structures to intricate forms over time. Competition affects the process of evolution in that the organism that is able to compete favorably for the available resources survives and continues to thrive, whereas the organism that cannot compete favorably dies and becomes extinct.

...Lab report Prediction of the Maximum Height Travelled By a Model Rocket The determination of rocket field is useful when in the quest for determining how high a rocket flies, at a given moment. In this lab, the major objective was to predict how high a rocket model could fly once launched. This involved acquiring a model rocket, then launching it to determine the figures for the various variables. Another related objective was to apply equations for basic projectile motion in determining how high a rocket can fly. Since launching the model rocket, this is considered a projectile motion influenced by height of launch pad, gravity and velocity imparted by the engine. Consequently, there...

...while in the case of measurement 2; it is 1.59m/s. 3 This lab experiment is relevant to many scenarios in life. When an object travels in the circular motion, its speed is constant which implies that the magnitude of the objects velocity is not changing while the direction changes. On a practical sense, the activity of driving around a curvy road is equivalent to this lab experiment. For a constant speed, tighter curves tend to generate a greater centripetal acceleration provided by the friction between the tires and the road. This can be described as follows: for steady speed, the equation of centripetal force has it that acceleration is indirectly proportional to the radii of the curve. When a car...

.... A normal pendulum with a few modifications can be used to achieve similar objectives. In this case, a zero position for the pendulum is identified. Since many labs are done on tabletops, the table top is assigned to be the zero height (mean) position. If the tabletop is designated the zero position, then the PE of an object is dependent on its relative height from the tabletop. Therefore, by obtaining the mass of the pendulum and its relative height from the table top, the gravitational potential energy can be calculated follow: PE = mass x relative height x Gravitational pull = mgh 2. As a car goes over a rough road or bumps, the spring in its shock-absorber setup is compressed, but the...
