Source of AC

  1. Jun 9, 2014 #1
    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?

    Either will do the job.

    A voltage source that produces AC is = a current source that produces AC ?

    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 text book are you studying from? It should have a table of symbols.

    Actually, none (for the time being). But, for show you that I'm not a lazy, look my collection of math and mechanics in anex.
