Finding a way to measure current was an important first step in early electricity.<\/p>\n<p>After the 1860s electric power use expanded with its largest growth period in the 1880s-1890s. This expansion depended on <a href=\"http:\/\/www.edisontechcenter.org\/electricmotors.html\">motors<\/a> and electric lights and it became necessary to have regular and accurate measurement of current. Technicians also needed the ability to bring meters out into the field to set up or troubleshoot systems. This need led to the development of portable ammeters.<\/p>\n<p>Lets start with the official UNIT 1 video:<\/p>\n<p style=\"text-align: center;\"><strong>\u00a0<iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/hlCHpkkmBdo?rel=0\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/strong><\/p>\n<p>Lets move on to our web course which starts with magnetism and ends with the pioneers of today&#8217;s greatest innovations in meters.<\/p>\n<p>&nbsp;<\/p>\n<table width=\"100%\">\n<tbody>\n<tr>\n<td>\n<div style=\"background: grey; float: left; text-align: center; line-height: 100px; width: 40%; margin: 10px; padding: 10px; box-shadow: 5px 5px 10px #000; min-height: 100px;\"><a style=\"text-decoration: none;\" href=\"http:\/\/www.edisontc.org\/ui\/home\/course\/\">Back<\/a><\/div>\n<div style=\"background: grey; float: right; text-align: center; line-height: 100px; width: 40%; margin: 10px; padding: 10px; box-shadow: 5px 5px 10px #000; min-height: 100px;\"><a style=\"text-decoration: none;\" href=\"http:\/\/www.edisontc.org\/ui\/home\/course\/unit-i\/galvanometers\/\">Next<\/a><\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Measuring voltage and current is the foundation of all electrical instruments.
