AP EAMCET · PHYSICS · Alternating Current
A coil of inductance and resistance is connected to a source of and . The phase difference between the voltage maximum and the current maximum is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
Inductive reactance is XL=ωL=2πfL=2π×350×0.1=219.9 Ω Now, total reactance is X=XL Phase difference is tanϕ=XR=219.9110=1.99≈2 Hence, phase difference between the voltage maximum and the current maximum is ϕ=tan-12.
