FINAL ANSWERS must be rounded up to three decimal places PROBLEM:A three-anode mercury-arc rectifier supplies a 250-kw 230-volt load and is energized from a 4,600-volt three-phase source through a three-phase transformer whose primaries are in delta. Assuming an arc drop of 20-volts, calculate:(a) the d-c load current;(b) the voltage and kilovolt-ampere rating of each transformer secondary;(c) the current and kilovolt-ampere rating of the three-phase transformer.

GIVE ME THE Numerical value not the formula.. WHATS THE ANSWER IN OHMS ?? Give answer as a Number NOT EQUATION 

A professor teaches two sections of a course: • 70% of students are in Section 1, and 30% are in Section 2. • In Section 1, 90% of students pass the final exam. • In Section 2, 80% of students pass the final exam. A student is randomly selected. a) Draw a tree diagram to represent this situation. b) What is the probability that the selected student passes the exam? c) Given that a student failed, what is the probability they were from Section 1?
