Hello,
I've always been a tinkerer my whole life, and I have a generally well rounded set of skills in terms of fixing things, taking them apart etc. I've always lived in small apartments and grew up in one so I never had the space to devote to doing anything properly... until now. I've built myself a little workshop in a walk-in closet in my apartment and I can finally do some proper tinkering. So, now in my 30's, i'd like to really start getting into electronics, circuitry etc.. but i'm starting basically from 0.
The internet is so full of information that its overwhelming and i'm finding it causes anxiety in terms of trying to figure out how to learn. So, as i've done with almost everything else i've learned, i figured the best way to start is by
doing. What i usually find myself doing is playing around with things i've taken apart, messing with batteries and power sources and seeing what works and what doesnt. So i've written down the most frequent questions I run into and hopefully by getting the answers i can start to understand the bigger picture. So here goes:
Thanks so much in advance for your answers

So i've written down the most frequent questions I run into and hopefully by getting the answers i can start to understand the bigger picture. So here goes:
- if the dc converter on a device is 9v 1amp, could you also use a 4.5v 2amp supply?
- I have a set of speakers which take 4 AA batteries or 6V but the DC charger is 9V, how come the two voltages work? why wouldnt the 9V fry the circuit board?
- Whats the difference between smaller / larger batteries with the same voltage? for example, lets say a 12v car battery and a smaller 12v battery. More / Less amps? (excluding obviously having longer capacity)
- What determines how much any given device can handle in terms of charge? for instance, why is it that some devices can work with less voltage or more voltage? how do i know whether a higher voltage / higher amp charge will ruin my device?
Thanks so much in advance for your answers
