In the field of electrical engineering, the distinction between "heavy current" and "light current" is traditionally based on the comparative strength of the electric currents utilized. While heavy current engineering focuses on power systems and apparatuses, light-current electronics engineering encompasses applications that process information or control systems using lower current levels.1
Technologies typically considered part of light-current electronics engineering include:
- Communication Systems: Such as telephone and radio networks.1
- Computing: The design and application of computers.1
- Control Systems: Automatic control systems used in various industrial and technical processes.1
- Detection and Imaging: Technologies such as radar, scintillation counters, and image intensifiers.12
- Optoelectronics: Devices that interact with light, including photodiodes, light-emitting diodes (LEDs), and laser diodes used in digital media and telecommunications.23
It is important to note that as technology has progressed, the boundary between these fields has become less sharp, as electronic devices are increasingly integrated into high-power systems for regulation and control.1
