alleryPhase relationships between voltage and current in an ac circuit are shown using:
APhasors
BPhrases
CPhotons
DPhonons
Answer & Solution
Correct answer: A. Phasors
1. Voltage and current in an ac circuit peak at different moments.
2. A rotating vector picture makes that offset visible.
3. To show phase relationship between voltage and current we use the notion of phasors.
4. So the answer is phasors.
