Question about voltage Answered
I am brand new here and have a question about voltage. I was reading the Instructable about how to run battery operated devices with ac power.
If I have a device that uses, for example three 1.5v batteries ill need to find an adapter that will push 4.5v. Is that correct? If that is correct, what would I do in this case? I have 20 of the same device, each of the devices take three 1.5v batteries. I want all 20 of these devices to be run on one wall plug(if possible). Does this mean that I need to get a wall plug that will push 90v? If thats the case, is that even possible? Thanks in advance
