B: Tikrit University has been established its electrical distribution system in a special method called RMU Ring Main Unit) which provide the University from two power sources (VA and VB) to ensure the continuity of the power for all buildings, if VA= 230 v and VB= 225 v determine: 1- Where will be the point of minimum potential (voltage) according to the sources VA and VB? Then explain why? 2- What are the highest and the lowest limits of voltages should be provided if the declared voltage is 224, in order to consider this distribution system is a good system?
