A milliampere (mA) is a unit of measurement, equal to a thousandth (that’s 10-3) of an ampere. An ampere (A) is a measure of an electric current, and you might read these measurements on household objects, such as flourescent lamps (56–112 mA), toasters and kettles (9A) or USB chargers (2A).
This is a general engineering zone, where you will meet six engineers all working in different areas. One designs and builds cameras that go to space, looking back at Earth or out to the stars, while another is trying to figure out how to recycle really big things like bikes, cars and even aeroplanes. One engineer is working on the Lightning II F-35B fighter plane, while another is an apprentice in the second year of a University degree. There’s also an engineer who works on the BT Sport App, using various tests and software to make sure users have the best experience, and another who processes hardware kits containing engine parts for aeroplanes worldwide.
