Circuit diagrams often show transistors in switching circuits. For an ideal NPN transistor, the switch-on voltage at the base is typically 0.6V (acceptable range is 0.6V to 0.8V).

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object ...

Transistors are tiny switches that can be triggered by electric signals. They are the basic building ... a switch with a signal from another switch. Here’s a relay circuit that performs ...

Water is usually something you’d want to keep away from electronic circuits, but engineers in Germany have now developed a new concept for water-based switches that are much faster than current ...
