Question

1. the resistance of a good inductor equals

±10% of the color code value
a small value
infinite ohms
0 ohms

Explanation:

A good inductor is designed to have low resistance. This is because the main function of an inductor is to store energy in a magnetic field, and a low - resistance path allows for efficient current flow with minimal power dissipation due to \(I^{2}R\) losses. Option A (\(\pm10\%\) of the color code value) is more relevant to resistors with tolerance. Option C (infinite ohms) would mean no current can flow, which is not the case for an inductor (it allows DC current to flow ideally with zero reactance for DC, but still has some small resistance in real - world good inductors). Option D (0 ohms) is an idealization. In practice, a good inductor has a small but non - zero resistance.

Answer:

B. a small value
