potential difference n. the difference in electric potential between two points, esp. in a circuit.

ΚΠ

1876 W. H. Preece & J. Sivewright Telegraphy 5 Potential implies that function of electricity which determines its motion from one point to another. And the difference of potential, which determines the amount of this motion, is called electro-motive force.]

1892 Jrnl. Inst. Electr. Engineers 21 606 If the currents and pressures were simple sine functions, then the power-factor in that case would be the cosine of the angle of lag of primary current behind the primary terminal potential difference.

1935 C. J. Smith Intermediate Physics (ed. 2) v. xlviii. 802 The potential difference across the coil is measured by the voltmeter V which is in parallel with the heating element.

1992 Professional Engin. Nov. 29/1 In galvanic (or self-driven) cells, such as batteries, fuel cells and some sensors, spontaneous chemical change gives rise to a potential difference which is used to drive current through an electrical load.
