Hello,

The internet has a heap of books and magazines.
I have collected links in this thread:

RE:""I have heard that there is a different voltage in the UK compared to USA""
Yes, sure, this is the most irritating thing for me on this Planet that humans cannot agree for ONE type of network voltage and plug dimensions.
Americans come with absolutely destructive 60 Hz and 110 Volts, Britts come with all things killing 240 Volts and hundred fuses in each kilogram sized plug (what, they not learned to put fuses into walls?), Polaks are murmuring about 230 Volts, all other lands are stick to 220/380 and 50 Hz, but soviet plugs are not valid for EU, and vice versa, Polish plugs may not be used in EU but EU may be used in PL, Pan Baltic plugs may be used in PL and rusia but no vice versa, Israel plugs may be used at Balticum but Baltic plugs may not be used in Israel and so on so on so on. Therefore I being rather easy movable human must have a full collection of hundreds different cross-plugs or how we call it "thieves". Its so damn heavy to take all time it with me!

Besides a recently imported virus, we also share with China, trains and the format of electrical plugs.

Some years ago, when I still used to travel more or less frequently abroad, I bought this that, albeit somewhat bulky, caters for all formats:





The white plug on the left, I bought it in UK to charge my tablet.

 

Janis59, you should read about the current wars, all about the development of AC and DC distribution systems at it's infancy. Start here: https://en.wikipedia.org/wiki/War_of_the_currents
There is also a new movie about this war. "It's easy for us a hundred years later to say we should have done..." Even Ben Franklin had a 50 percent chance of getting polarity right and missed.



"Franklin was the first to label them as positive and negative respectively,[50][51] and he was the first to discover the principle of conservation of charge.[52] In 1748, he constructed a multiple plate capacitor, that he called an "electrical battery" (not to be confused with Volta's pile) by placing eleven panes of glass sandwiched between lead plates, suspended with silk cords and connected by wires.[53] " from https://en.wikipedia.org/wiki/Benjamin_Franklin#Electricity

 

Voltage and current deals with the same fundamental concepts, doesn't matter from which place you are. If you are a beginner in this field, let's start with minimum voltage 1.2V AA Cell and move forwards with LED Blinking, DC Motor operating and continue...

There are many platforms from which you can learn electronics. like, Moonshot Jr ,Hackster.io, Instructables etc

 

Since the crank winds a spring, it's synchronized only in the crudest sense.

Many had a Fly-ball govenor arrangement.

@alex.will Year old thread BTW!
Max.

 

Ain't it synchronized to your arm cranking?

No
