Объяснение: Electronic circuits are integral parts of nearly all the technological advances being made in our lives today. Television, radio, phones and computers immediately come to mind, but electronics are also used in automobiles, kitchen appliances, medical equipment and industrial controls. At the heart of these devices are active components, or components of the circuit that electronically control electron flow, like semiconductors. However, these devices could not function without much simpler, passive components that predate semiconductors by many decades. Unlike active components, passive components, such as resistors, capacitors and inductors, can't control the electron flow with electronic signals.
Irkutsk (52 degrees 17 minutes north latitude, 104 degrees 16 minutes east longitude) is located approximately at latitude cities such as Orenburg, Saratov, Voronezh, Warsaw, Berlin.
