Transistors are inevitable parts of Electronic circuits. The success of a circuit design lies in the selection of proper transistor type and calculation of voltage and current flowing through it. A ...

This simple circuit has helped me out on many occasions. It is able to check transistors, in the circuit, down to 40 ohms across the collector-base or base-emitter junctions. It can also check the ...

If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs, switch a ...

Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light. Last ...

[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a cheap ...

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 sophisticated ...

At the center of modern technology lies the logic circuitry provided by semiconductor devices. Extending circuit logic to the realm of nanotechnology requires the construction of atomic-scale systems, ...

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 \(0.7 V\).

Scientists have created a thermoelectric organic transistor. A temperature rise of a single degree is sufficient to cause a detectable current modulation in the transistor. Scientists have created a ...
