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 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 […]
What are the forms of iron ore?
What are the forms of iron ore? Iron ore mining methods vary by the type of ore being mined. There are four main types of iron ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits. What are the 4 types […]
How does an air powered car work?
How does an air powered car work? For compressed-air cars, the power plant’s electricity is transmitted to a compressor, which mechanically compresses the air into the car’s tank. The car’s engine then converts the compressed air to mechanical energy. What energy does wind have? kinetic energy Is there a car that runs on air? In […]
What are the three parts of a lamp?
What are the three parts of a lamp? Parts of a light bulb: the glass globe, the metal filament, wires and glass stem, gases and metal base. What are parts of a lamp? Parts of a Table Lamp (top to bottom): Lock: Locks the lampshade in place. Lampshade fitting: structural frame for the lampshade. Lampshade: […]
Does the Fermi level depend on temperature?
Does the Fermi level depend on temperature? The experiment shows that the Fermi level decreases with increasing temperature and has almost the same temperature dependence as the energy gap. It is pinned at about 0.63 of energy gap below the conduction band. How is Fermi level calculated? You can use our Fermi level calculator to […]
How many coordinate systems are there?
How many coordinate systems are there? In this article we mainly discuss two types of coordinate systems. What is the difference between phi and theta? Theta is the same as the angle used in polar coordinates. Phi is the angle between the z-axis and the line connecting the origin and the point. How do you […]
What is the cycle of rain called?
What is the cycle of rain called? As the water vapor rises higher and higher, the cool air of the atmosphere causes the water vapor to turn back into liquid water, creating clouds. This process is called condensation. When a cloud becomes full of liquid water, it falls from the sky as rain or snow—also […]
How far did Amelia Earhart fly?
How far did Amelia Earhart fly? 2,000 miles Who piloted the first non-stop flight across the Atlantic? The First Nonstop Flight Across the Atlantic Lasted 16 Harrowing Hours. John Alcock and Arthur Whitten Brown flew across the Atlantic with the help of a sextant, whisky and coffee in 1919—eight years before Charles Lindbergh’s flight. Who […]
Is triode a diode?
Is triode a diode? Triode tubes A triode is much like the diode vacuum tube, except that it has an additional part: a metal wire grid, between the heated filament and plate. The small radio signal coming from the antenna is fed into the grid, and it greatly alters the voltage flowing through the triode. […]
