In the circuit shown below- a capacitor is being used in an AC circuit. A magnetic needle shows deflection, both at point P and Q. Which of the options among the following correctly specifies the reason for the presence of magnetic field at both the points?
- A Due to conduction current and displacement current at Q and P respectively .
- B Flow of charges in the wire and constant electric field between the plates \(A\) and \(B\).
- C Flow of charges in the wire and varying electric field between capacitor plates \(A\) and \(B\).
- D At \(Q\) the magnetic needle will show deflection due to magnetic field of the earth and at \(P\) due to the current flowing in the wire.
Answer & Solution
Correct Answer
(C) Flow of charges in the wire and varying electric field between capacitor plates \(A\) and \(B\).
Step-by-step Solution
Detailed explanation
Flow of charges in the wire and varying electric field between capacitor plates A and B. At Point P: The magnetic needle deflects because of the conduction current ( \(I_c\) ) flowing through the wire. This current is the physical flow of charges (electrons), which generates a…
