These are some questions which my teacher told us would likely be on a test tomorrow. I'd just like to know the best possible answers for them, as I have a general idea but I'd like to be sure. 1. Why are loads connected in a household in parallel rather than series? 2. Why must transformers use AC to work? 3. How do transformers use safe and efficient distribution methods for electrical energy? 4. Describe the basis of electrical generation. 5. Describe the historical reasoning from electrical current and why it goes in the opposite direction? Thanks a lot guys!
