Ammeter in both vanes, the vanes repel each other and the moving vane deflects against the restoring force provided by fine helical springs. The deflection of a moving iron meter is proportional to the square of the current. Consequently, such meters would normally have a non linear scale, but the iron parts are usually modified in shape to make the scale fairly linear over most of its range. Moving iron instruments indicate the RMS value of any AC waveform applied. Moving iron ammeters are commonly used to measure current in industrial frequency AC circuits. In a hot-wire ammeter, a current passes
Electrical Water Pageant the Main Street Electrical Parade at Disneyland, an oscillator swoop was heard during the music transitions in the Electrical Water Pageant. The 1972 to 1976 lineup of floats for the Electrical Water Pageant were: With the return of the Disneyland Main Street Electrical Parade in an updated form along with the brand new Walt Disney World Main Street Electrical Parade, a new version of Jean-Jacques Perry & Gershon Kingsley's "Baroque Hoedown" was created in 1977 to be used with both parades respectively featuring an updated rendition of Barque Hoedown recorded by Don Dorsey. To help distinguish the Electrical Water Pageant
