2-5) AC-AC Phase

Question 1

What is the term used to describe two sine waves that are at the same frequency but not in step or synchronized with each other?

Answer 1

Out of phase

Question 2

What is the term used to describe two sine waves that are at the same frequency and are in step or synchronized with each other?

Answer 2

In Phase

Question 3

What is the Phase Shift between A & B? Describe the phase relationship.

Answer 3

90 degree phase shift. A leads B by 90 degrees. B lags A by 90 degrees.

Question 4

What is the Phase Shift between A & B? Describe the phase relationship.

Answer 4

90 degree phase shift. B leads A by 90 degrees. A lags B by 90 degrees.

Question 5

What is the Phase Shift between A & B? Describe the phase relationship.

Answer 5

A and B are 180 degrees out of phase with each other. A leads B by 180 degrees. B lags A by 180 degrees. A and B waveforms are mirror images of each other. A and B are inverted.

Question 6

What is the Phase Shift between A & B? Describe the phase relationship.

Answer 6

There is a 0 degree phase shift. A and B are in phase with each other.

Question 7

What term is used to describe the number of degrees apart that 2 waveforms are out of sync?

Answer 7

Phase shift
