AC Theory - Production of the AC Sine Wave

AC generators require three items to function. What are they?

• gasoline, turbines, gears

• conductor, magnetic field, relative motion

• peak to peak, effective value, instantaneous

• height, width, depth

AC generators convert ___________ energy to ____________energy.

• pressure/force

• mechanical/electrical

• chemical/electrical

• kinetic/relative

Four designations to measure current and voltage associated with AC sine waves are: (select all that apply)

• Peak

• Peak-to-Peak

• Root mean square (RMS)

• Average

When a conductor cuts through 10 million lines of flux in 1 second, it will produce how many volts?

• 1

• 10

• 100

• 1000

As a generator armature makes one full revolution, it goes through ? degrees of mechanical rotation.

• 0

• 90

• 270

• 360

The AC voltage waveform is in the positive direction for some period of time and in the negative direction for some period of time. What is the name given to this waveform?

• alternating wave

• inverted wave

• hertz wave

• sine wave

The plotted resulting waveform as the conductor rotates in a magnetic field follows ? .

• the angle of the rotation

• the cosine of the angle of the rotation

• the sine of the angle of the rotation

• the tangent of the angle of the rotation

At what degrees on the sine wave is the voltage equal to zero?

• 0 deg, 90 deg, 270 deg

• 0 deg, 90 deg, 360 deg

• 0 deg, 120 deg, 360 deg

• 0 deg, 180 deg, 360 deg

When a conductor cuts the magnetic flux lines at ? , the maximum voltage will be induced into the conductor.

• 60 deg

• 90 deg

• 180 deg

• 360 deg

Sine waves are so named because the voltage at any point along the wave form is equal to the maximum, or peak, value times the ? of the angle of rotation.

• cosine

• degree

• sine

• tangent
