I was wanting to get some hands on experience with AC current circuits. I have been tinkering with DC circuits on a breadboard and was wondering what the best way to get AC on a breadboard would be. I can't really spend 200+ on a function generator. I might spend 30 or so on a kit function generator if that is what I need. I also of course can't buy an oscilloscope. So my question I suppose is, is a kit function generator worth it for an amateur hobbyist? And, why can't I just mimic AC using oscillating circuits of some sort? Thanks.
