I am aware that AA batteries are calculated in terms of Ah and not A, and volts, still is there any way to calculate how much current in A that 3 AA batteries can produce? The details, First, I don't have much understanding of electricity. I do not try to deal with any electric related stuff but this felt simple so I thought of trying. Son has Snap Circuit sets that use 3 AA batteries. Now that he has a lot of time on hand and gets bored easily, he is running batteries like a set per 6 hours/day or so. He is using rechargeable batteries, still, I thought maybe it is easier to just put it on USB power using a phone power bank. Did some YouTubing and found a guy using dowels https:/
/ Only difference is, he used a transformer and I chose to use a phone power bank. I was just focused on 5V produced by 3 batteries. I 'assumed' the current drawn will be dependent on the circuit. Snap Circuit didn't like these batteries and they didn't work (but worked with 3 AA batteries). Everything seemed OK so I tried in one of the LED lamps I had that uses 3 AA batteries. It lit up but soon one of the functions failed. It has On/Off/Auto setting. The auto setting has a motion-sensing sensor. Now it works on On but not on Auto. I opened up the lamp and smelled something burnt.
I am quite confused about why it stopped functioning and smell something burnt. Is it because the current was too high from the power bank (between 1-2.5A). And why the LED lamp works but Snap Circuit doesn't.
Any educated guesses?
(P.S. - I admit, many may not know what circuits I am talking about but I don't know how best I can put this question. Pls ask if any more info needed.) www.youtube.com/ watch?v=UzruV5pH1RU
