For the most part you just need ohms' law..
For your motors you would need to look at the NEC motor Tables, NEC 430-248-252 and obtain your current then apply ohms law.

Since you are a student, work on converting the loads to wattage and show us what you find.
You will get more out of it that way than us giving you the answers.

At my age, I'm accustomed to restaurants asking me to pay in advance, but now my bank has started sending me their calendar one month at a time.
