Electric Circuits and Gadgets -- Basics Please

Well, when I lived in India, I remembered a neighbor whose occupation was creating little gadgets, such as watches, lasers, etc.

I am now living in Pakistan, and missed the chance of asking the guy how he learned what he knew.

I am curious to just basically learn what are the functions of basic hardware components that creates such hardware.

Can anyone give me a runway of this field, and give me a sense of how different components come together to operate a gadget?
I apologize if my English is not good, but it is not my first language and I am only 14 years old.

Welcome to the PF.

Your question is a bit overly broad -- too broad to be able to give a good answer, I believe. I'd suggest using wikipedia.org to look up different gadgets that you are interested in learning about, and then if you are confused about some specific issue, post your question here with a link to the reading you have been doing.

The website HowStuffWorks.com may also be a good place for you to do some reading. My dad got hard copies of the HowStuffWorks books when I was about your age, and reading through those books was a huge help in forming my mental pictures of how things operate and how to build them...

I am quite baffled were to start. Thank you for the website references and the book recommendation.

Can you please give me a few gadgets to explore?

Because I remember when I first started learning physics with optics without having a solid idea of electrostatics--not so intuitive.

Thank you in advance!

I think I'd just start browsing around the HowStuffWorks.com website, and check out some of the tabs on the main page like Autos, Science, etc.

Here are a few fun things to learn about:

http://auto.howstuffworks.com/auto-parts

http://electronics.howstuffworks.com/transistor.htm

http://science.howstuffworks.com/transport/flight/modern/airplanes.htm

...and so on...
