Another bit of historical geekery, the Megger. In these days of practically anything and everything being “Mega”, the Megger was eponymously named as it’s purpose was to measure electrical resistance in the range of “megohms”, a megohm being one million ohms, which is a lot. It was often used as a practical joke device whereby unsuspecting apprentices would be tole to hold the terminals whilst the wicked perpetrator wound the handle causing a humorous electric shock to be imparted to the foolish victim.
