Good question. Traditionally, there is a distinction between "electrical", which can involve wires, resistors, capacitors, and inductors (including electromagnets, and so relays), and "electronic", which includes vacuum tubes like diodes, triodes, pentodes, & cathode ray tubes, and semiconductor devices like transistors. If I recall correctly, World War II technology mostly used electronics for radio communication and radar.
