Generating Electrical Power Flashcards
1
Q
What produces alternating current?
A
Rotating the coils or the magnet (electromagnetic induction)
2
Q
What is meant when an AC waveform is described as ‘sinusoidal’?
A
It slowly moves from peak flow in one direction to peak flow in the other
3
Q
What does the term ‘phase’ describe?
A
The position of a waveform, either a long a time continuum or in terms of degrees or radians.
4
Q
What does that term phase shift describe?
A
Permanent or temporary displacement of a wave form along the continuum.
5
Q
What is the unit for ac power and what are AC generators in?
A
The volt-amp, AC generators are rated in kilovoltamps (kVA)
