Ammeter Ammeter An ammeter (from Ampere Meter) is a measuring instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as "milliammeters" or "microammeters". Early ammeters were laboratory instruments which relied on the Earth's magnetic field for operation. By the late 19th century, improved instruments were designed which could be mounted in any position and allowed accurate measurements in electric power systems. It is generally represented by letter 'A' in a circle. Ammeters have very low resistance and
Electrical Water Pageant premiers of the updated version of the Disneyland Main Street Electrical Parade and new (but similar) Walt Disney World Main Street Electrical Parade used a new version of "Baroque Hoedown" updated by Don Dorsey. The original lineup of floats for the Electrical Water Pageant were: While the 1971 version of "Baroque Hoedown" would play along with the Electrical Water Pageant through 1976, Disney melodies were added to the track and some of the floats were repositioned and others completely changed in 1972; and remained that way through 1976. While the track was essentially the same as what was heard during
