General exam question G5C14
Subelement G5, ELECTRICAL PRINCIPLES· Group G5C
Which of the following components should be added to an inductor to increase the inductance?
- A.A capacitor in series
- B.A capacitor in parallel
- C.An inductor in parallel
- D.An inductor in series (correct answer)
WhyAdding an inductor in series with an inductor increases the total inductance. Inductance adds directly when inductors are placed in series (assuming no significant mutual coupling), so adding an inductor in series increases total inductance, answer D. Inductors in parallel reduce total inductance rather than increasing it, and capacitors, whether in series or parallel, don't add to an inductor's inductance at all, so A, B, and C are wrong.
