A potentiometer is an instrument for measuring the potential (voltage) in a circuit. Before the introduction of the moving coil and digital volt meters, potentiometers were used in measuring voltage, hence the '-meter' part of their name. The method was described by Johann Christian Poggendorff around 1841 and became a standard laboratory measuring technique.
In this arrangement, a fraction of a known voltage from a resistive slide wire is compared with an unknown voltage by means of a galvanometer. The sliding contact or wiper of the potentiometer is adjusted and the galvanometer briefly connected between the sliding contact and the unknown voltage. The deflection of the galvanometer is observed and the sliding tap adjusted until the galvanometer no longer deflects from zero. At that point the galvanometer draws no current from the unknown source, and the magnitude of voltage can be calculated from the position of the sliding contact.
This null balance measuring method is still important in electrical metrology and standards work and is also used in other areas of electronics.
A measuring instrument is a device for measuring a physical quantity. In the physical sciences, quality assurance, and engineering, measurement is the activity of obtaining and comparing physical quantities of real-world objects and events. Established standard objects and events are used as units, and the process of measurement gives a number relating the item under study and the referenced unit of measurement. Measuring instruments, and formal test methods which define the instrument's use, are the means by which these relations of numbers are obtained. All measuring instruments are subject to varying degrees of instrument error and measurement uncertainty.
Instrument is a documentary film directed by Jem Cohen about the band Fugazi. Cohen's relationship with band member Ian MacKaye extends back to the 1970s when the two met in high school in Washington, D.C.. The film takes its title from the Fugazi song of the same name, from their 1993 album, In on the Kill Taker.
Editing of the film was done by both Cohen and the members of the band over the course of five years. It was shot from 1987 through 1998 on super 8, 16mm and video and is composed mainly of footage of concerts, interviews with the band members, practices, tours and time spent in the studio recording their 1995 album, Red Medicine.
The film also includes portraits of fans as well as interviews with them at various Fugazi shows around the United States throughout the years. The Instrument Soundtrack by Fugazi was released in conjunction with the film. It consisted primarily of instrumental and unreleased songs (including many demo cuts from End Hits, their next album after the soundtrack).
The soundtrack mostly consists of previously unreleased songs and studio outtakes culled from Fugazi's history to that point, as well as seven demo versions of songs from their proper albums (six from 1998's End Hits and one from 1993's In on the Kill Taker).
Of particular note is the song "I'm So Tired", a piano ballad played and sung by Ian MacKaye, which is a significant departure from Fugazi's usual post-hardcore sound.
The riff from "Lusty Scripps" was played in Fugazi's final live show, in the break between the main set and the encore.

#UnacademyJEE #electricalmeasuringinstruments #JEE2022 #jeephysics
A potentiometer is an instrument for measuring the potential (voltage) in a circuit. Before the introduction of the moving coil and digital volt meters, potentiometers were used in measuring voltage, hence the '-meter' part of their name. The method was described by Johann Christian Poggendorff around 1841 and became a standard laboratory measuring technique.
In this arrangement, a fraction of a known voltage from a resistive slide wire is compared with an unknown voltage by means of a galvanometer. The sliding contact or wiper of the potentiometer is adjusted and the galvanometer briefly connected between the sliding contact and the unknown voltage. The deflection of the galvanometer is observed and the sliding tap adjusted until the galvanometer no longer deflects from zero. At that point the galvanometer draws no current from the unknown source, and the magnitude of voltage can be calculated from the position of the sliding contact.
This null balance measuring method is still important in electrical metrology and standards work and is also used in other areas of electronics.
