What causes high total harmonic distortion? Harmonic distortions are usually caused by the use of nonlinear loads by the end users of electricity. Nonlinear loads, a vast majority of which are loads with power electronic devices, draw current in a nonsinusoidal manner. What does total harmonic distortion mean? From Wikipedia, the free encyclopedia. The total […]
Why do metals typically have larger thermal expansion coefficients than ceramics?
Why do metals typically have larger thermal expansion coefficients than ceramics? In contrast, materials such as stainless steel possess weaker bonds between atoms, resulting in much higher coefficients of thermal expansion in comparison with Fine Ceramics. Why do ceramic materials have small coefficients of expansion? In ceramic materials, the atoms are not free to move […]
Which is correct Please find attached or please find the attached?
Which is correct Please find attached or please find the attached? For example, say “Please, find the attached file you requested yesterday.” When you don’t want to specify any particular file, avoid using “the”. You can simply write, “Please, find attached.” or its abbreviated form: PFA. “Attached” is the correct word for electronic communications. How […]

How much entropy is in the universe?
How much entropy is in the universe? The total entropy of the observable universe is correspondingly higher, and is Sobs = 3.1+3.0−1.7 × 10104 k. Will the universe end? If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over […]
What factors affect lift and drag?
What factors affect lift and drag? Lift and drag also vary directly with the density of the air. Density is affected by several factors: pressure, temperature, and humidity. At an altitude of 18,000 feet, the density of the air has one-half the density of air at sea level. What factors affect drag force? Which are […]
Which cycle is more efficient for electricity generation plant?
Which cycle is more efficient for electricity generation plant? A combined-cycle power plant uses both a gas and a steam turbine together to produce up to 50 percent more electricity from the same fuel than a traditional simple-cycle plant. The waste heat from the gas turbine is routed to the nearby steam turbine, which generates […]
What is horizontal position in welding?
What is horizontal position in welding? The welding position in which the weld is on the upper side of an approximately horizontal surface and against an approximately vertical surface. What are the position of welding? What Is a Welding Position? Flat position. Also referred to as a “downhand” position, the flat position weld is the […]
