What Is a Transistor? (Definition, How It Works, Example) | Built In
网页A transistor is a device that controls an electrical current by acting as an amplifier or a switch. As an amplifier, a transistor can increase the electrical output, even if the input is small. As a switch, a transistor can alternate between ‘on’ and ‘off’ phases to manage the electrical current .
