Ammeter the effect – the instruments were called "multipliers". The word "rheoscope" as a detector of electrical currents was coined by Sir Charles Wheatstone about 1840 but is no longer used to describe electrical instruments. The word makeup is similar to that of "rheostat" (also coined by Wheatstone) which was a device used to adjust the current in a circuit. Rheostat is a historical term for a variable resistance, though unlike rheoscope may still be encountered. The D'Arsonval galvanometer is a moving coil ammeter. It uses magnetic deflection, where current passing through a coil placed in the magnetic field of a
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.
