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 :

Options

  1. AA, B and C only
  2. BA and B only
  3. CB, C and D only
  4. DA, B and D only

Correct answer

D. A, B and D only

Step-by-step solution

This is possible when phase difference is 2 between current and voltage so correct answer will be (4)
