The first transistor was about half an inch high. That's mammoth by today's standards, when 7 million transistors can fit on a single computer chip. It was nevertheless an amazing piece of technology.

A transistor – a word blend of "transfer" and "resistor" – is a fundamental component of today's advanced electronics. Essentially, a transistor, as one of the foundational elements of modern ...

Process devices operate when an input level, such as voltage, reaches the required value for the device to operate. The transistor is on, when the input voltage is greater than or equal to \(0.7 V\).
