We’re talking about two separate parts of the Transistor Man diagram here, the base-emitter junction, which is a diode, and the collector-emitter circuit, which is not a potentiometer.

A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types to more ...

Witness how transistors work together in intricate circuits, powering the systems that run code, execute commands, and drive all your digital experiences. Metal Workers Posted: June 11, 2025 ...

Figure 1 The XOR logic element and its analog using discrete elements.. The second variant of the 2XOR element is shown in Figure 2.Transistors Q1 and Q2, as well as resistor R2, serve as the 2AND ...

Ideally a circuit that use one socket, and can both ID it as a NPN or PNP, and ID the leads as a bonus. In the meantime I have my BK Precision in circuit transistor test that does that. A nice ...

The diode T1 must be positioned away from the heat source to ensure that it is always at room temperature. The circuit “measures” the heat difference between the transistor and the diode. T2 should ...

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 ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...

The team designed a paper-based amplifier-type circuit that incorporated resistors, capacitors and a transistor. They first used wax to print channels onto a sheet of paper in a simple pattern. After ...

A simple electric circuit learns to classify data in a creative new design that could lead to more energy-efficient machine-learning hardware. The creative new approach could lead to more energy ...
