I have a "newbie" question about battery current

AWOL:

Electronics are so expensive

No, happily, they're about as ludicrously cheap as I can ever remember them.

Correct, but I guess it depends on the users definition of 'electronics'. Apple iPhones are expensive but raw electronic components have never been cheaper in my lifetime as they are now, plus the internet opens up a worldwide seller/buyer connection making component selection and purchases easier then ever.

Bottom line, there has never been a better time to enjoy electronics as a hobby.
