3D stereoscopic video was first implemented in July 2009. [80] In September 2011, a "2D-to-3D conversion tool" was added. [81] Side-by-side 3D videos could be made to appear as stereoscopic 3D (anaglyph 3D). Since late 2018, it is only available with a flag set in the video file's metadata. [82] [83]
A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit. It is connected in parallel . It usually has a high resistance so that it takes negligible current from the circuit.
Dailymotion, a French video-sharing website, is founded. [19] 2005 April 23 Companies YouTube opens for video uploads, and the first YouTube video uploaded on April 23, 2005, is titled Me at the zoo. [20] Between March and July 2006, YouTube grows from 30 to 100 million views of videos per day. 2006 May 14 Companies
The Model EA113 was an excellent electronic multimeter, sold in the UK and abroad, in the same style as the Model 14 to 21 range. Avometer model numbers were first used by the company from 1936 (Avometer Model 7) and were used to distinguish designs with different ranges and functionality. Several "Models" were in production contemporaneously.
Coulometers can be used to determine electric quantities in the direct current circuit, namely the total charge or a constant current. These devices invented by Michael Faraday were used frequently in the 19th century and in the first half of the 20th century. In the past, the coulometers of that type were named voltameters.
The first Avometer was made by the Automatic Coil Winder and Electrical Equipment Co. in 1923, and measured direct voltage, direct current and resistance. [1] Possibly the best known multimeter of the range was the Model 8, which was produced in various versions from May 1951 until 2008; the last version was the Mark 7.
Analog multimeter Digital multimeter. A multimeter (also known as a volt-ohm-milliammeter, volt-ohmmeter or VOM) [1] is a measuring instrument that can measure multiple electrical properties. [2] [3] A typical multimeter can measure voltage, resistance, and current, [4] in which case can be used as a voltmeter, ohmmeter, and ammeter.
A modern electrometer is a highly sensitive electronic voltmeter whose input impedance is so high that the current flowing into it can be considered, for most practical purposes, to be zero. The actual value of input resistance for modern electronic electrometers is around 10 14 Ω, compared to around 10 10 Ω for nanovoltmeters. [ 9 ]
