Answer 1

Ответ:

используя переменный ток стандартной частоты мы можем решить данную задачу

Answer 2

It seems like you provided some information about an electrical circuit, but it is not clear what you are asking. The symbols "U=220V" and "I=2.5A" likely represent the voltage and current values, respectively. However, "С-??????????" is not clear.

If you meant to ask for the value of the unknown component represented by "С," please provide more context or clarify your question, and I'd be happy to help you further.
