Description: | UNIVERSITY OF GLASGOW APPLIED PHYSICS DEPARTMENT (embossed on a metal label on the box). Sir William Thomson (written in pencil on the inside bottom of the box). Put plugs in outer circle of coils capacity equal to one microfarad when all pluds are in (written in pencil on the inside of the lid of the box).. Condenser Test 1902 4 coil is broken down completely and must always be left with its plug in inner hole to use any other section put its plug in outer hole . Sections not in use should................(very very written in ink on a linen label attached to the handle ofthe box, removed). SIR WILLIAM THOMSON 1 Microfarad No. 101 W. M. Warden & Co.

DES after MAXWELL,James,Clerk,Professor. circa 1870 DES THOMSON,William,Lord,1st Baron Kelvin of Largs. circa 1870 DES after VOLTA,Alessandro,Giuseppe,Anastasio,Count. 1778 Pavia. Italy MANU W. M. Warden & Company. circa 1870 Westminster, London, Eng This pattern sometimes called a standard air condenser was developed from an idea suggested to Kelvin by Clerk Maxwell. This type of instrument is now called a capacitor. It has two pairs of circular plates in a vertical stack. Electric charge builds up on plate until the resistance of the air gap between them breaks down and electricity passes to the mext plate. The total amount of electricity that the condenser can store, or its capacitance, is determined by the surface area of the plates, the distance between the plates, and the conductivity of the dielectric medium. When all the plates are charged to capacity and the condenser is connected to earth it discharges and the process then starts again. | License: | http://www.hmag.gla.ac.uk/spirit/rights/ | Publisher: | Hunterian Museum and Art Gallery, University of Glasgow | Rights holder: | Hunterian Museum and Art Gallery, University of Glasgow | Subjects: | SCIENTIFIC COLLECTION : | Source: | Hunterian Museum | Creator: | Hunterian Museum and Art Gallery, University of Glasgow | Identifier: | http://www.huntsearch.gla.ac.uk/cgi-bin/... | Language: | en-GB | Go to resource |
