Electric current

Background Information Electricity is a form of energy resulting from the build-up of charged particles, either statically as an accumulation of charge or dynamically as a current (Oxford dictionary, 2015). The effect of electricity can be seen in play daily, whether through a simple light bulb, or a complex application such as providing energy to a power plant. It is often stated that electricity is the most versatile and easily controlled form of energy, and at the point of use it is…

solid-state based LED point-light sources. Introduction-An OLED (organic light-emitting diode) is a sort of LED (light-emitting diode), where the emissive electroluminescent level is a film of organic compound which releases light in response to an electric current. This layer of organic semiconductor material…

Problem: The research questions being examined in this investigation is, How can we generate electricity by using Potatoes to light an electric bulb? Background Information: How does a potato battery work? The copper (Cu) particles pull in electrons more than the zinc (Zn) molecules. On the off chance that you put a portion of copper and a piece of zinc in contact with each other, numerous electrons go from the zinc to the copper. As they focus on the copper, the electrons repulse each other.…

material resists current, and is measured in Ohm-meters (Ω-m). Electrical resistance (R) is the opposite of the flow of electrons, or the passage of an electrical current. Electrical conductivity (σ) is the opposite of resistivity and is measured in Siemens (S). Electrical conductivity is defined as; the degree to which a specified material conducts electricity, calculated as the ratio of the current density in the material to the electric field which causes the flow of current. In this…

The first part of the experiment was determining the resolution of the DAC in volts. Before a voltage was applied the noise was determined by measuring the DC offset, the reading of the DMM at an input of zero volts. This offset was removed from the recorded values in order to provide a more accurate reading of the resolution. These corrected values and their corresponding applied voltages can be found in Table 1 of the appendix. The lowest value recorded from the DMM was -9.968V and the…

Mechanical power is defined as torque and RPM (rotation per minute) and electric power is defined as current and voltage. Therefore, in order convert mechanical power into electric power, torque shall be converted into current and rpm shall be changed into voltage. The relation between the rpm and voltage can be defined with equations with the use of Equations. When there is a decrease in value in equations there is an increase in efficiency of power generator. In here, there is no loss when…

What is a circuit? How do they work? An electric circuit is a kind of path made up of wires that allows the flow of electrons. The circuit has to be made in a circular form, as the electrons must frequently move in a full loop, in which they will return to their original position and then complete the loop again. (“What is an electric circuit?”) The battery or another source of power provides the voltage, or ‘electrical push’, that makes the electrons move through the circuit. When the electrons…

In this experiment, various electrochemical cells were measured and calculated to determine their electrical cell potential. In the electrochemical cell Zn (s) │Zn2+ (0.10 M) ││ Cu2+ (0.10 M) │ Cu(s), E cell potential was determined to be 1.040 V while the standard E˚ cell potential was 1.10 V. In the electrochemical cell Zn (s) │Zn2+ (0.10 M) ││ Cu2+ (1.0 M) │ Cu(s) E cell potential was determined to be 1.060 V while the standard E˚ cell potential was 1.10 V. In the electrochemical cell Cu (s)…

The third component will begin in July 2017, which involves understanding our Electronic Medical Records (EMR) and hiring a trained professional who has extensive knowledge pertaining to MIPS. Therefore, the first activity in component three is to ensure our EMR, eClinical, is sufficient enough to handle the MIPS reporting data. For example, the EMR needs to be able to extract quality measures in order for our organization to report to CMS by the end of the 2017 fiscal year. In this activity,…

A memo describes a project that Mildred re-surfacing and reconfiguration. From this memo, I found several pieces of the design could be improved. Also, I agree with some good decisions made by the author. First of all, the wording choice in this memo is easy to understand. The vocabularies in this memo usually have one meaning. For instance, on the first point of “What will they do,” it directly indicates that they will reduce Mildred Street from a 5 to 3 roadway. This makes readers not confused…
