Transistors are solid state electronic switches. Solid state means that there are no moving parts, and the switching action is regulated by the arrangement…
A resistive transducer is a device that senses a change to cause a change in resistance. Transducers do NOT generate electricity. Examples include: Device Action Where used Light Dependent Resistor…
Silicon Diodes and Zener Diodes Diodes are one-way electrical valves that allow current to flow in one direction only. Click HERE to…
Grounding In many circuits, a zero reference point is shown connected to earth, or grounded. In this circuit, the point Y has been connected to ground, and…
Logic gates are at the heart of digital electronics. In digital electronics, we need to know nothing about electricity, other than the…
Electronic systems consist of: · An input device to sense changes, e.g. a light detector · A processor that responds to the change · An output device that enables…
