    Even my 1929 book entitled "Mechanical World Electrical Pocket Book" advertising Brook motors on the front cover, uses a small v for Volts. GGGGRRRRRRRRRrrrrrrrrrrrrrrrrrrrrrrrrrrrrr.


    That is no way to show respect for poor old Alessandro.


    So, we use a big V when it has a number in front of it like 400 V, but a small v when referring to an unspecified number like "low voltage".
