What happens when you disconnect an inductor? When your inductor is suddenly disconnected from its source, the inductor now becomes the source and it wants to keep the current flowing in the same direction it was going; ie the current does not reverse! You can see this visually by connecting a scope across the inductor. […]
How do you calculate core loss of a transformer?
How do you calculate core loss of a transformer? What is Core Loss in transformer? With Calculation and Formula No machine is 100 percent efficient all over the world, there are always losses! I2R. In other words, these domains act like very small magnets randomly placed in the structure of the material. Pe=KeB2f2t2V in Watts. […]
How do you find the heat transfer coefficient of a Nusselt number?
How do you find the heat transfer coefficient of a Nusselt number? Formula Nusselt Number : Nu = hL/k. Convection Heat Transfer Coefficient : k = Nuk/L. Characteristic Length : L = Nuk/h. Thermal Conductivity of the Fluid : k = hL/Nu. Where, Nu = Nusselt Number, h = Convection Heat Transfer Coefficient, L = […]
Why was New Orleans not prepared for Hurricane Katrina?
Why was New Orleans not prepared for Hurricane Katrina? Emergency managers in New Orleans had been debating whether the levee system would work in a major hurricane before Katrina hit. Federal funding cuts left many projects undone and local engineers were not surprised when water surged into New Orleans. How did the federal government fail […]

What is one way the Maori genealogies and origins in New Zealand contrasts with the Raven and the First Men the beginnings of the Haida quizlet? What is one way that “The Maori: Genealogies and Origins in New Zealand” contrasts with “The Raven and the First Men: The Beginnings of the Haida”? The Maori myth […]
How can the motion of fluids be described?
How can the motion of fluids be described? There are two ways to describe the fluid motion. One is called Lagrangian, where one follows all fluid particles and describes the variations around each fluid particle along its trajectory. The other is Eulerian, where the variations are described at all fixed stations as a function of […]
