Two AC waveforms have the same frequency, but their cycles do not begin at the same instant. What term describes that timing difference?
- APhase
- BPolarity
- COffset
- DDelta
Correct answer: A — Phase. From the official ISED question bank, verified word for word.
Why
Phase describes the timing difference between two waveforms of the same frequency when their cycles do not start at the same instant. The full explanation — and one for every question — is in Pro.
