Learn AC current and voltage by every electric machine or electronic circuit you know

[sonny]

I want to learn how AC works and I have no idea what I should use as an AC source since I never used one.I only know of inverters but that's not really helping me in understanding RLC circuits....Are AC sources real?Are they batteries?I'm new in this and I can't think of a device or something that allows me to learn how the voltage and current change from negative to positive in the AC.Also I don't want sockets as an example.

 

[sonny]

Anyone?

There are AC sources just about everywhere.
If you want a safe supply for testing purposes, then you should obtain an isolated power supply.
These devices use a 1 to 1 transformer to isolate the supply from the mains.

You mean an inverter?Is that what this is supposed to be?

That's a transformer.What does this have to do with what I want?Are you saying that you use a transformer for an inverter?I don't understand what you are saying.I wanted to know if it is possible to change a DC 1,5v baterry with a transformer to an AC voltage of 220-230 v.

I'm not 100% sure if this works because I've never touched an inverter nor created one.

Can you make a circuit for an isolated power supply as you suggested?I searched google and found some circuits.
Here is an image of an isolated power supply:

AC alternates because it is produced by rotating magnets.
When the magnet is pointing up, the AC is positive, when the magnet is pointing down, the AC is negative.

AC can come from invertors, but mostly it comes from alternators
NOT generators, generators produce DC, alternators produce AC.

Sounds to me like you are yet to get your head around basic theory,
So I suggest you do just that,read up on basic theory.
When you have come back and ask questions that you can then get your head around.
So So little grass hopper.

Sonny, you are trying to run here before you can walk, you need to go to basics and learn about the subject, there are no short cuts to understanding it so you need to learn the basics, AC passes through the zero volts and reverses DC does not but can have a waveform in its own right, perfect DC is a straight line on a graph.

AC can come from invertors, but mostly it comes from alternators
NOT generators, generators produce DC, alternators produce AC.

Slightly correct but not fully - The alternator and generator both works on the principle of Faraday law of electromagnetic induction. The generator induces both the alternating and direct current and the alternator produces only alternating current.

Probably meant say dynamo instead of generator.

Hi Sonny - could I suggest you read up on the topic? This link has some explanations (hopefully accurate ...).
