(12)A voltmeter reads 110 V when connected across the terminals of a sinusoidal power source with f = 2000 Hz. What is the equation for the instantaneous voltage provided by the source?
(A)v = (110V)sin(12566t)
(B)v = (110V)sin(6280t)
(C)v = (156V)sin(6280t)
(D)v = (156V)sin(12566t)
(E)v = (190V)sin(12566t)
