Question
Which of the following components should be added to an inductor to increase the inductance?
Answer Options
- A) A capacitor in series
- B) A capacitor in parallel
- C) An inductor in parallel
- D) An inductor in series
Correct Answer: D
Explanation
Inductance is a measure of a coil’s ability to store energy in a magnetic field. To increase the total inductance of a circuit, the coils must be connected in a way that maximizes the total magnetic field storage.
For an inductor, this is achieved by adding an inductor in series. When inductors are connected in series (and assuming no mutual coupling), the total inductance is the simple sum of the individual inductances (L_T = L_1 + L_2 + \dots). Connecting them in parallel would reduce the total inductance.
