MCQ
What will be the phase difference between virtual voltage and virtual current, when the current in the circuit is wattless.....$^o$
- ✓$90$
- B$45$
- C$180$
- D$60$
✓
Answer
Correct option: A.
$90$
a
(a) If the current is wattless then power is zero. Hence phase difference $\phi = {90^o}$
(a) If the current is wattless then power is zero. Hence phase difference $\phi = {90^o}$
