• 1879, Oliver J. Lodge, “On a Modification of Mance's Method of Measuring Battery Resistance”, in Proceedings of the Physical Society of London : From November 1875 to December 1878, volume 2, London: Taylor & Francis, page 147:

  And the reason of this is apparent, viz. that the opposition experienced by a current in passing through an electromotor is of two kinds—one due to the proper ohmic resistance, the other due to the electromotive force; and with only one strength of current it is no more possible to tell how much of the opposition is resistance and how much is electromotive force, than it is to obtain the values of two unknown quantities from one equation.

• 1904 November, “Single-Phase Compensated Motor Equipment in Operation on the Ballston Division of the Schenectady Railway”, in [Bulletin of] General Electric Company, Railway Department, number 4392, page 4:

  With the alternating current system using a trolley and track return there is an inductive drop in the trolley and rails, with an additional loss in the latter case due to eddy currents and hysteresis. Measurements made upon the Ballston line indicate an apparent trolley resistance of 1.3 times the ohmic resistance, and a rail resistance of 6.55 times the ohmic resistance.

• 1910 December, Philip R. Alger, “Professional Notes: Wireless Telegraphy and Telephony”, in United States Naval Institute Proceedings, volume 36, number 4 (or 136), Annapolis, Maryland: U. S. Naval Institute, page 1200:

  In wireless telephony there are various systems of influencing the radiations by the use of the microphone. In the simplest method, which has been adopted by De Forest, Fessenden, Poulsen, Majorana and others, the microphone is intercalated in the circuit of the transmitting antenna, so as to vary the ohmic resistance of the circuit. This process, however, can be used only for communication over a very short distance with small power.
