Prior to the transistor’s discovery in 1947, the only way to execute amplification of a weak current in an electronic circuit was to use a vacuum tube. What were the initial advantages transistors demonstrated over small vacuum tubes?
Варианты ответа:
- Transistors had longer lifespan, were smaller and many of them could be placed on a single chip
- Transistors were larger, while consuming far less power. They were more reliable
- Small vacuum tubes’ production cost was much higher. Tubes’ material turned out to be harmful for people’s skin
