Current source

not many people are interested in history. Before taking this class I thought history was a boring subject that I would not need later in life. Through this class I have learned that it is important to know what you are talking about, to look at sources carefully, and that history can be important to me in my future career. Through this class I have learned that it is important to gain as much information as possible to a subject that you are arguing about. This was an important lesson to learn…

function as both light source and color array at the same time; they are used to generate digital displays in devices. Due to their early stage of improvement, they normally release fewer lights per unit area than inorganic 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…

Direct Current (DC) motors Name: University 1.0 Introduction A Direct Current (DC) motor is one of the broader classification of electric motors which operate from a direct current. Nearly all mechanical devices applied in daily life activities are powered by electric motors. Motors transform electrical energy to mechanical energy, hence they are essential for energy conversions in electrical machines. All types of electrical motors are made up of a stationary field referred to a stator and…

Established in 2002, this program partners with other agencies to provide healthcare services to a demanding population. Their current workforce development program has 4 pillars to include: 1. Professional development, 2. Academic achievement, 3. Customized skill development/enhancement and 4. Career counseling. For professional development, Trinity Health Center offers training…

6/10/2015 Mrs Rummins | GRUJICIC, Marko Background: Another name for I/V characteristics is current-voltage. Current and voltage are the factors that are being investigated, there characteristics and effects in diodes of different colours. The Current or I in I/V characteristics refers to the flow of an electric charge. It is often carried out by electrons when moving through wires Materials: -green, red, blue, yellow coloured diodes -breadboard -wires - 2X multimeters, 1 as a voltmeter…

To do Cable calculation it has to meet the requirements from BS 7671. Design Current First thing to do is calculate the design current. (Ib) I=Watts/Volts. You do this so you can find out the total current. Apply Diversity Factors (where applicable) Diversity is described in the onsite guide Appendix A as a way to determine the maximum demand for an installation and includes the current demand for commonly used equipment. For example if in a domestic household there were 8 lights on a…

alternating current which means that the current flows in both directions. So instead of flowing from one source to another, the current can flow from both the source and the recipient to each other. AC voltage is the current that comes from an electrical plug. An advantage of AC voltage is the fact that the power of the voltage can be altered with a transformer. Fig.1 graph showing AC and DC current On the other hand DC voltage stands for direct current. This means that the current only…

generating station 's electrical power distribution system, which provided 110 volts direct current (DC) to 59 customers in lower Manhattan. However Edison became stuck, as in order for his system to work he would need to have power stations scattered every mile to make it economical. Which wouldn’t work, the reason being that to bury the cables would be very expensive and the cables would also lose current over long distances, because of the resistance inside…

energy source because, physics would not allow it, also there is no physical evidence to prove this energy source, and most websites that claim he did are not credible. First, I need to clarify what I mean when I say Free/Alternative energy. Free energy is the creation of energy (electricity) without actually using any resources (non-renewable and renewable) at the same time. Alternative energy is an energy created through the use of renewable energy source, most common alternative energy…

were the only source of light, transport was steam-powered, food was stored in ice boxes. However, within the next fifty years, electricity would change that. In 1878, Thomas Edison invented the incandescent lightbulb; in 1888, Frank Sprague’s electric trolley system became the first large-scale electric rail system in the world; in 1911, General Electric unveiled the first electric refrigerator. However, the rise of electricity was fraught with conflict over the type of electrical current.…
