Electrical discharge

Study of patterns produced by electrical discharges on surfaces revealed by dusting with powdered red lead and sulphur. Sometimes termed 'Lichtenberg figures'. These experiments were conducted at Cragside in Northumberland, England, using a Wimshurst machine (electrostatic generator) and two 10-gallon Leiden jars. Current was conveyed to two rod conductors with a spark gap at which coated wires discs or plates were positioned. Lord Armstrong exhibited figures of the type produced at the Royal Society soiree at Burlington House in London on 16 June 1897. Plate 5 from Supplement to Lord Armstong's work on electric movement in air and water...by William George Armstrong and Henry Stroud (London, Smith Elder & Co., 1899). The plate is inscribed below: "Plate V. NEGATIVE DISCHARGE BETWEEN CENTRAL WIRE (NEGATIVE) ABOVE, AND METAL RING (POSITIVE) BELOW THE VARNISHED PLATE" William George Armstrong, Baron Armstrong (1810-1900) armaments manufacturer and industrialist was elected a Fellow of the Royal Society in 1846.
