Deep Dive: G5C14
The correct answer is D: An inductor in series. The component that should be added to an inductor to increase the inductance is an inductor in series. Series inductors add directly, increasing total inductance. For amateur radio operators, this is a basic series inductance principle. Understanding this helps when designing circuits.
Why Other Answers Are Wrong
Option A: Incorrect. A capacitor in series doesn't increase inductance - capacitors affect capacitance, not inductance. Series capacitor doesn't help. Option B: Incorrect. A capacitor in parallel doesn't increase inductance - capacitors affect capacitance, not inductance. Parallel capacitor doesn't help. Option C: Incorrect. An inductor in parallel decreases total inductance - parallel inductors use reciprocal formula, reducing inductance. Parallel inductor doesn't increase inductance.
Exam Tip
Increase inductance = add inductor in series. Think 'I'ncrease 'I'nductance = 'I'n series 'I'nductors add. Series inductors add directly, increasing total inductance. Not capacitor, not parallel inductor - just series inductor.
Memory Aid
Increase inductance = add inductor in series. Think 'I'ncrease 'I'nductance = 'I'n series. Series inductors add directly, increasing total inductance. Standard way to increase inductance.
Real-World Example
You have a 10 mH inductor and want more inductance. You add a 20 mH inductor in series. Total inductance = 10 + 20 = 30 mH. Series inductors add directly, increasing total inductance. This is how you increase inductance.
