A 2-wire DC distributor AB is fed at both ends at the same voltage of 230 V. The length of the distributor is 500 m and the loads are tapped from the end A as shown below: Load (A) Distance(m) 100 50 60 150 40 250 100 400 If the maximum voltage drop of 5.5 V is to be allowed, find the X-sectional area of each conductor and point of minimum potential. Specific resistance of conductor material may be taken as 1.73×10-8 №.m. [1.06 cm²; 250 m from A]

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.
