Ammeter through a wire which expands as it heats. Although these instruments have slow response time and low accuracy, they were sometimes used in measuring radio-frequency current. These also measure true RMS for an applied AC. In much the same way as the analogue ammeter formed the basis for a wide variety of derived meters, including voltmeters, the basic mechanism for a digital meter is a digital voltmeter mechanism, and other types of meter are built around this. Digital ammeter designs use a shunt resistor to produce a calibrated voltage proportional to the current flowing. This voltage is then measured by
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
