I want to know the answer to the following question:
What type of losses happen during conversion and transmission in wires and electronics?
All the background I'm provided with is that "Power conversion for a DC system takes place mainly in a railway substation where large, heavy, and more efficient hardware can be used as compared to an AC system where conversion takes place aboard the locomotive where space is limited and losses are significantly higher.". Is that enough to answer the question?
Answer: no
