Wussup with Ammeters and Voltmeters?

A shout-out to Anja, for producing this video explaining how ammeters and voltmeters are set up, i.e. what the circuitry is in order for these devices to give us measurements of currents and voltage differences. Many thanks!


  1. The video is not showing up on my computer; instead it has a link to screentoaster. Is anyone else having this problem?

  2. For measuring current in industrial and scientific equipment, the zero center ammeters are used. To operate the zero center ammeters, the ammeters are placed with a battery in series. This way, the charging battery deflects the measuring needle aside usually the right side. Discharging the battery will deflect to the opposite side. To read more about ammeters and multimeters follow onto the next page.
