What are the advantages of having high amperage? By the way, I'm rather new to electronics. I know that having high-voltage reduces the energy loss through the wire, and you don't need as thick a wire. But I cannot find the advantages of high amperage on the internet. This may be due to my bad wording of the question, or due to my lack of knowledge on the subject, however I still would like to know. Thanks for any help, in advance.
