Electrical Engineering What is the smallest square box that will accommodate four No. 12 conductors and four No. 10 conductors if a. These conductors are pulled through without a splice? b. These conductors are all spliced in the box?

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.

Choose the correct answer. *Please answer it ASAP if you can
