Home » Electric Circuits » Electric circuits miscellaneous » Question

The value of the capacitance C in the given ac circuit to make it a constant resistance circuit OR for the supply current to be independent of its frequency is

1. 1 F
  16
2. 1 F
  12
3. 1 F
  8
4. 1 F
  4

Correct Option: A

For constant resistance, equating imaginary term to zero,

16 +
