The core of a transformer operating at 50 Hz has an eddy current loss of 100 W/m3 and the corelaminations have a thickness of 0.50 mm. The core is redesigned so as to operate with the same eddycurrent loss but at a different voltage and at a frequency of 250 Hz. Assuming that at the new voltage themaximum flux density is one-third of its original value and the resistivity of the core remains unaltered,determine the necessary new thickness of the laminations. Clear and detailed solution.
one turn of a copper bar is produced by cutting copper washer along a radius and spreading the ends. The washer is cut from soft drawn copper having a resistivity at 20 degrees celsiu of 1.732 micro ohm-cm. The washer is 0.125 inch thich and has inside diameter and outside dianmeter of 1 inch and 9 inches respectively. Calculate the exact resistance between the two end of the turn. Assume the contact along the ends of the turn to be perfect over the entire crown section.
