Electrical resistance

I graduated from the University of Houston, Texas with a Master of Science degree in Electrical Engineering with Thesis in May 2011. My engineering work experience as an Engineer-In-Training began at En-Fab, Inc. in Houston, Texas from June 2011 and since then I am working as an Electrical Engineer in this company. My engineering experience at En-Fab, Inc. entailed being a member of the project engineering group where I performed calculations for sizing of the motor and branch circuit overload…

Multimeter: A device used to measure the amount of amperes, volts, and ohms over several ranges of value. Conductor: Object allowing the transfer of electrons Insulator: Prevention of an object receiving an electric current. Resistance: Prevents passage of normal current (light bulb or LED; the object) Parallel: each resistor or light is independent. If one goes out, the rest still stay one. Series: each light is dependent on another one. If one goes out, so do the rest. Scientists…

practically loss-free and essentially non-polluting (I.E.C., 2015). However, as with most energy, electricity experiences a force that acts against its efficiency, known as resistivity or resistance. Resistivity is the material property that pertains to how difficult it is for…

Electrical Properties AC Conductivity, Ac Resistivity, Dielectric loss, and Dielectric constant are electrical properties and measured as a function of frequency. AC Conductivity and Resistivity AC resistance (ρac) was recorded by LCR meter model 4275 in the frequency range 1MHz to 3GHz. AC conductivity was determined by using the value of Ac resistance. As we know, Ac Conductivity is reciprocal of Ac resistance can be calculated by the relation; ac =1/ρac (6) The variation of AC…

considered a wheel and axle because it contains a wheel that is attached to an axle that allows for the wheel to move and helps magnify the force you exert. Ramp: A ramp is considered an incline plane because it permits you to overcome a large resistance, by applying a small force through a longer distance when raising the load. Jack Screw: A jack screw is considered a screw because it contains a modification of an inclined plane and requires a force over a greater distance while exerting a…

William Wade Unit 303 Task A 21/10/2016 1. A fault has occurred on the electric shower in one of the rooms. It was reported that • The shower was switched on. • A crackling sound was heard coming from the shower. • The lights in the room flickered and dimmed. • The shower went off. Describe the likely faults that could produce these symptoms. Lose terminal connections in the shower system could have caused the shower to crackle due to arching…

inventions. Edison is best known for creating a commercially viable light bulb, and Tesla is remembered for his contributions to the design of alternating current electricity. Though Edison is more well known, both men contributed greatly to the field of electrical science and should forever be remembered. Thomas Edison was born on February 11th, 1847. He grew up in Milan, Ohio, and later moved to Michigan. As a child, he was highly intelligent and showed…

an essential part is to evaluate the losses in the motor. Losses in the machine is determined by the structure and working condition. Losses in the machines can generally be divided into two groups: electrical losses and mechanical losses. Electrical loss indicates the losses generated by the electrical interacting and circuit heat generating in the machine, generally includes copper loss and iron loss (also known as core loss). Mechanical loss is mainly generated by the friction in the machine…

Edison’s dream would quickly become a reality as large cities with power stations began adopting Edison’s DC electrical grid. However, it would take the work of Tesla and Westinghouse before the modern AC/DC current would be created. The alternating current could more easily be converted into high voltages, which are easily transported over large distances with fewer losses due to resistance that occurs naturally in any type of wire. This allowed a smaller number of power stations to provide…

Analyse the values of voltages in generation, transmission and distribution? Task 4 (D1) Electricity has greatly evolved from what it once was, to be fit for our modern day consumption and usage. Electrical engineering was first pioneered in the early 19th century, and great progress had been made by the time the 19th century came to a close. Most of the advancements were made by the likes of Thomas Edison, Nikola Tesla and George Westinghouse; who all aided in making electricity what it is…
