Origin: Formed within English, by compounding. Etymons: water n., resistance n.

Etymology: < water n. + resistance n. With sense 1 compare air resistance n. at air n.¹ Compounds 2. In sense 3 after water-resistant adj.

1. The resistance that water offers to something moving through it. Cf. air resistance n. at air n.¹ Compounds 2.

1827 N. Arnott Elements Physics I. i. 55 Air resistance, to motions going on in air, is of the very same nature as water resistance, to motions going on under water, only less in degree.

1894 T. Parker in J. H. Greathead & F. Fox Liverpool Overhead Railway 28 The tests were taken after the engine had been running the traffic all day, when the load was transferred to a water-resistance tank.

1908 Jrnl. Royal Soc. Arts 56 546/2 Their effect depends upon the water resistance set up against the rolling motion itself.

2009 M. Denny Float your Boat! ii. 51 Before we can understand how the boat moves, however, we need to consider water resistance.

2. An electrical resistance formed by two electrodes partly immersed in an aqueous solution; (also) resistance offered by water to an electric current.
