Flashcards in L2 week3 Deck (16):
Angular measurement equal to 1/360 of the circumference of a circle.
Angle formed when the distance along the circumference of a circle equal the radius of the circle.
The ratio of the circumference of a circle to its diameter. Has a constant value ≈ 3.1416
Angular measurements can be made in
degrees or radians.
There are ...... or ...... radians in one complete revolution.
360 or 2pi
The positive amplitude in the sine wave is equal to
the middle of the sine wave is equal to
the negative amplitude in the sine wave is equal to
Angular measurement that specifies the position on the sine wave relative to a reference point.
Sine wave shifted right
lags (-ve phase shift)
Sine wave shifted left
leads (+ve phase shift)
Occurs when a sine wave is shifted right or left in relation to the base/reference sine wave.
An important application of phase-shifted sine waves is in
electrical power systems
