Atransistor is an active semiconductor device with three or more electrodes.by active (подразумевается is meant) that the transistor is capable of current gain, voltage amplification and power gain. a transistor is an electronic device in which electronic conduction (производится is performed) within a semiconductor. a semiconductor is an electric conductor with resistivity in the range between metals and insulators, in which the electrical charge carrier concentration (увеличивается grows) with increasing temperature over some temperature range. the resistivitiys of semiconductors and insulators (уменьшается falls) rapidly with rising temperatures, while those of metals (увеличевается goes up) relatively slow.

Ur travel continuуd two рours in heat. when we came to the train station, we understood   that it   was three hours before for train. time passed slowly and we got bored of doing   nothing.after train announced we were very happy, but happines wasnt long. everywhere was dust and dirt. all noght someone screamed and played loud music.two years ago i was in camp. i got there by train with group of chirdren that came to the same camp. i was there three weeks.in the morning i pulled out my dress, whicch wanted to wear and left it on my bed. when i got back there wasnt dress. i was broken.as a result i came home tired angry and without dress. i was unhappy.   it was the worst expereance of   traveling by trainon the way back home we were very unlucky, at first, we spent four hours waiting for the bus. when it arrived and we got inside we were very angry because it was without condition and chairs were broken and dirty.
