JEE Main 2024 Physics question
In an ac circuit, the instantaneous current is zero, when the instantaneous voltage is maximum. In this case, the source may be connected to: A. pure inductor. B. pure capacitor. C. pure resistor. D. combination of an inductor and capacitor. Choose the correct answer from the options given below:
Answer: (D)
Solution
A 90° phase difference between V and I occurs for a pure L, a pure C and an ideal LC combination; a resistor has zero phase difference.
