This circuit has a very low current flow. Because of the input power of 1.5 watts, I estimate the output current to be about .05 milliamps. This is far below the lethal amperage of 100 miliamps.
I have learned these electrical theories through years of personal study. I have used YouTube and many old books from the sixties to learn what I know. As far as I know, they do not teach electronics in school. It is pretty sad, because it is a very fun hobby that combines physics, math, and good old engineering skills. I agree, many kids and teens do not want to create new things, they just like to play video games and like you said, "Watch". I think that our world would be a better place if every kid tried building things. Thanks for commenting, and by the way, nice pun at the end of your comment!
Yes, a battery would be able to power this circuit. This particular device only draws about 1.5 watts.
