When a circuit is being alimented by AC this means that exist in the circuit a voltage source that is generating the AC or exist a current source that is generating the AC?
Understanding the Source of AC in Circuit Alimentation
In summary, the conversation discusses the difference between voltage source and current source in an AC circuit. Both can produce AC and can be transformed freely between each other. The symbol shown is an AC voltage source and current source symbols usually have an arrow. There is no specific textbook being studied, but the person has a collection of math and mechanics resources.

Either will do the job.

Voltage source plus resistor in series is a current source; current source with a resistance in parallel is a votage source. They can be transformed freely, and thus either can be an AC source.

but this guy:

represents a current source or a voltage source?

That symbol is an AC voltage source ... the same circle as for a DC voltage, but since the +/- changes with time the squiggle represents the sine wave.
Current source symbols usually have an arrow.
What textbook are you studying from? It should have a table of symbols.

1. What is AC in circuit alimentation?
AC stands for alternating current, which is a type of electrical current that periodically reverses direction. In circuit alimentation, it refers to the alternating current that is used to power electronic devices.
2. How is AC generated in a circuit?
AC is generated in a circuit by using a power source, such as a generator or power plant, to produce a continuous flow of electrons. This flow of electrons is then converted into AC by using a device called an alternator or inverter.
3. What is the difference between AC and DC?
The main difference between AC (alternating current) and DC (direct current) is the direction in which the electrons flow. In AC, the electrons periodically change direction, while in DC, they flow in one direction. AC is also able to be easily converted to different voltages, while DC cannot.
4. How does AC power affect electronic devices?
AC power is the most common type of power used to operate electronic devices. It provides a consistent and efficient source of energy that can be easily transformed into different voltages, making it ideal for powering a variety of devices.
5. What are the safety considerations when working with AC in circuit alimentation?
When working with AC in circuit alimentation, it is important to take proper safety precautions to avoid electrical shocks. This includes using insulated tools, wearing protective gear, and ensuring that the power is turned off before working on any circuit. It is also important to follow proper wiring and grounding techniques to prevent electrical hazards.
