   • 1900, Journal of the Franklin Institute, volume 149, page 461:

     If the volt, ampere and ohm were taken as the absolute units, the practical units would be the ampere, begohm and begavolt, names just as convenient as ampere, coulomb and farad.

   • 1992, Chilton's General Motors, page 7:

     As the test light voltage touches terminal "C7", the module should switch, causing the ohmmeter to "overrange" if the meter is in the 1000-2000 ohms position.
