COMEDK · Physics · 23. Alternating Current
In which of the following circuit do we find the current and voltage in phase?
- A A purely capacitive circuit
- B A circuit in which an inductor and a capacitor are in series.
- C A purely inductive circuit
- D A purely resistive circuit
Answer & Solution
Correct Answer
(D) A purely resistive circuit
Step-by-step Solution
Detailed explanation
In an AC circuit, the phase relationship between voltage \(V\) and current \(I\) depends on the nature of the components present. For a purely capacitive circuit, the current leads the voltage by a phase angle of \(\dfrac{\pi}{2}\). For a purely inductive circuit, the current…
