Lamination of core increases resistance to circulating eddy currents, reducing eddy current losses (I²R). Hysteresis loss reduced by using soft iron. Copper loss is in windings. Lamination is insulation between layers.
Explanation:
Diamonds are cut in such a way that light entering them hits multiple facets from the inside at an angle greater than the critical angle (which is very low for diamond, around 24.4°). This results in multiple total internal reflections, trapping light and forcing it out of specific faces, creating a brilliant sparkle.
Explanation:
Uranium-235 undergoes fission most efficiently when struck by slow-moving (thermal) neutrons. However, fission reactions release very fast-moving neutrons. The moderator (like graphite or heavy water) collides with these fast neutrons to slow them down without absorbing them, sustaining the controlled chain reaction. Control rods (cadmium/boron) are used to absorb excess neutrons.
