Reading time: 3 minute The power supply supplies power to all other units on the ECU. In a car, the available voltage source is the battery, which in operation has terminals 13.5 - 14V. This voltage value can vary depending on several factors. Every functional block needs constant voltage to function properly.
Reading time: 2 minute The purpose of this article is to present the functionality of electronic control units in the automotive field and to understand the interconnections of functional blocks.
Reading time: 2 minute In the practice of radio amateurs, very often there is the problem of making and measuring inductors with a value between 1.5 - 16 uH. The article presents a simple device, easy to make, designed for measuring coils with small inductors.
Reading time: 2 minute Electrical fuses, regardless of their type and the place where they are used, have a single purpose: they disconnect the electrical circuits when through them an abnormally high consumption occurs.
Reading time: 3 minute Approximately 85% of turbine components, including steel, copper cables, electronics and gear can be recycled or reused. But fiberglass blades are difficult to remove.
Reading time: 3 minute Wind turbines are equipment that transforms the kinetic energy of the wind into mechanical energy. Mechanical energy is further transformed into electricity, which is delivered in the public electricity network, stored in batteries or consumed directly.
Reading time: 4 minute The alternator is actually an electric generator. Its rotor is driven by the car engine through a drive belt. By rotating the rotor, which is actually a magnet, an induced voltage appears inside the stator.
Reading time: 2 minute Just as heat accelerates the chemical reactions in lead-acid batteries, cold temperatures slow them down. At lower temperatures, the battery's ability to provide enough power to start and run a vehicle is diminished.
Reading time: 2 minute The diagrams, summaries and tables in the textbook highlight significant aspects for students' learning acquisitions. The conclusive examples and the types of problems solved are well chosen and sufficient in quantity.
