Прочитайте текст и определите какой из заголовков соответствует тексту Alternating current a.c. is c...: ответ на тест 606826 - Английский язык

Прочитайте текст и определите, какой из заголовков соответствует тексту
Alternating current (a.c.) is converted into direct current by means of a rectifier.
A half-wave rectifier consists of a diode in series with a resistance. In order to put a rectifier into operation, a source of a.c. should be applied to it. When an a.c. source is applied the diode begins to conduct. The rectifier passes currents during positive half-cycles of the applied voltage. That is why it is called a half-wave rectifier. When the device operates direct current (d.c.) flows in the same direction. It is a pulsating current. Since pulsations should be eliminated, a filter is applied. Pulsations are eliminated by means of this filter.
