USC-led SWIFT project aims to reinvent the transistor using waves of magnetism, potentially slashing energy use and cooling costs, while helping GPS resist jamming ...

Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...

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 . . .
