We power a large amount of devices with electricity. Professionals working with electricity, e.g. electrical engineers, use lots of different units of measurements. On top of amperes they might work with coulombs or ohms.
This is a general engineering zone with six engineers from different backgrounds. One makes the water flushed from toilets drinkable, one builds wind farms in Africa and one studies how to create new smart and flexible wings for airplanes. One 3D prints spaceships, satellites and armoured fighting vehicles out of metal, one manages distance learning programmes, and another designs systems that drive trains automatically.
