Electromagnetism is the study of the physical interaction that happens among electrically charged particles. This electromagnetic force is typically apparent in magnetic fields‚ electric fields and sources of light. This electromagnetic force that occurs between particles is one of the four ultimate interfaces in nature. On April 8‚ 1911 in Leiden‚ Heike Kamerlingh Onnes discovered Superconductivity. Superconductivity is the phenomenon when a material cooled below a certain temperature emits no electromagnetic

oppose the coil’s motion‚ which serves to adjust the position of the needle to indicate the correct voltage. What is an Ammeter? Ammeters are used to measure the current in electricity in amperes. Named after French scientist Andre-Marie Ampere‚ amperes are a unit of measurement for determining the amount of electricity moving through a circuit. Ampere’s Law simply states that the magnetic field within a closed loop is proportional to the

VINEGAR (ACETIC ACID) AS ALTERNATIVE BATTERY Battery or more precisely‚ a cell – is a device in which the reaction between two substances can be made to occur in such a way that some of the chemical energy is converted to useful electricity. Since its invention‚ the battery has become the most common power source for many household and industrial applications. There are many ways to construct a battery‚ as well as ways to control its generated output. This Home-made Vinegar Battery is a battery

Measurements of Capacitance and Inductance Purpose: To use equipment and techniques to determine the structure of a hidden series RLC circuit and to measure the values of the various components in that circuit. Theory: To see how an RLC circuit works‚ consider the circuit in Figure 1 with the capacitor initially charged. Fig. 1 RLC Circuit Since there is a conducting wire connecting the negative side of the capacitor to the positive‚ a current will begin to flow in the counterclockwise

Michael Leung History 11CP Research Paper 16 March 2016 Word Count: 753 Thomas Edison v. Nikola Tesla The late 19th century sparked the time of electricity‚ where two famous innovators‚ Thomas Edison and Nikola Tesla‚ Thomas Edison and Nikola Tesla brought this to the world with their battles between electricity. They both influenced each other‚ although never agreeing together. Edison and Tesla were different inventors from other inventors during their time‚ but they contributed

Performance Analysis of OFDM Systems using Cooperative Diversity Techniques Abstrac t: Cooperative Diversity has been widely used in wireless network‚ and Orthogonal frequency division multiplexing (OFDM) is a key technique of multi-carrier transmission to meet high data rate requirement of wireless communication. The aim of this project is to combine the technology of OFDM with cooperative diversity techniques. The simulation will be done in MATLAB. The performance of the system will be compared

EXPOSITORY ESSAY FOR THE HOUSE By: McClain Baxley A circuit is a closed loop that electrons can travel in. A source of electricity‚ such as a battery‚ provides electrical energy in the circuit. Unless the circuit is complete‚ that is‚ making a full circle back to the electrical source‚ no electrons will move. There are three essential parts to a true circuit. These include electrical devices. An electrical device is a device that resists the flow of energy. Another electrical device that a successful

The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. It is also now widely recognized that the fossil fuels and other conventional resources‚ presently being used for generation of electrical energy‚ may not be either sufficient or suitable to keep pace with ever increasing demand of the electrical energy of the world. Also generation of electrical power by coal based steam power plants or nuclear power plants
