What will be the phase difference between virtual voltage and virtual current when current in the circuit is wattless?
- A \(60^ \circ\)
- B \(45^ \circ\)
- C \(90^ \circ\)
- D \(180^ \circ\)
Answer & Solution
Correct Answer
(C) \(90^ \circ\)
Step-by-step Solution
Detailed explanation
When current in the circuit is wattless, \(\cos \phi=0\)
\(\therefore \quad\) Phase difference is:
\(\phi=90^{\circ}\)
\(\therefore \quad\) Phase difference is:
\(\phi=90^{\circ}\)
