Unit I Measuring Electricity

Measuring voltage and current is the foundation of all electrical instruments. In Unit one we cover the journey from magnetic and chemical devices to the solid state devices of today.

It can’t be expressed enough how important instrumentation is for the electrical industry. Finding a way to measure current was an important first step in early electricity.

After the 1860s electric power use expanded with its largest growth period in the 1880s-1890s. This expansion depended on motors 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.

Lets start with the official UNIT 1 video:

 

Lets move on to our web course which starts with magnetism and ends with the pioneers of today’s greatest innovations in meters.
