The development of screen-printable electronic ink for flexible electronics.
Electrical engineering and electronics engineering are closely related fields concerned with the practical applications of electricity. While electronics engineering is technically a branch of electrical engineering, they are often distinguished by the scale and nature of the electric currents they utilize.21
Key Distinctions
- Electrical Engineering: Often referred to as the field of "heavy current," it focuses on electric power systems, including the generation, transmission, and distribution of electricity. This includes working with turbines, generators, transformers, and motors.23
- Electronics Engineering: Known as the field of "light current," it deals with the electromagnetic spectrum and the application of devices like transistors and integrated circuits. Its applications include computers, telecommunications, radar, and control systems.23
Modern Convergence
The boundary between these fields has become increasingly blurred due to technological progress. Modern power systems now frequently integrate electronic devices for control and conversion, while computers are essential for managing complex power grids.2
