Scientific Instument, Hewittic Rectifiers, X-Ray Tube, 1956
This item was acquired by the Ballarat School of Mines Electrical Engineering department for use in electric power laboratory as a source of D.C., and also for instructional purposes. This central mercury arc element was located in a cabinet with transparent side panels, and equipped with the required electric accessories, to be a self-contained stand-alone unit. Head of the Electrical Engineering Department at the time was John M. Sutherland.Mercury arc rectifier, 3-phase input. Constructed of blown glass, and complicated configuration: the central inverted truncated cone is provided with 3 large diameter "horns' and four smaller ones. Each horn has electrical connection to outside, some have side horns. Approximately half a cup of free mercury inside the glass complex.

Scientific Instument, Capacitor
... as 10,000 µF. scientific instrument capacitor electrical engineering ...DEFINITION microfarad Posted by: Margaret Rouse WhatIs.com Contributor(s): Kenda, Jack Clements The microfarad (symbolized µF) is a unit of capacitance, equivalent to 0.000001 (10 to the -6th power) farad. The microfarad is a moderate unit of capacitance. In utility alternating-current (AC) and audio-frequency (AF) circuits, capacitors with values on the order of 1 µF or more are common. At radio frequencies (RF), a smaller unit, the picofarad (pF), is often used. This unit is equal to .000000000001 (10^-12) µF. In RF scenarios, capacitances range from about 1 pF to 1,000 pF in tuned circuits, and from about 0.001 µF to 0.1 µF for blocking and bypassing. At audio frequencies (AF), capacitances range from about 0.1 µF to 100 µF. In power-supply filters, capacitances can be as high as 10,000 µF. Capacitor, 1/3 M.F.D.
