a measured value of 100 ohm and the another has a measured value of 10 Ohm.Which inductor would you choose to use in a circuit where the narrowest possible bandwidth is required and why? A. Use 100 Ohm inductor because it has a higher Q. B. Use the 100 Ohm inductor because it has a lower Q. C . Use 10 Ohm inductor because it has a higher Q D.Use the 10 Ohm inductor because it has a lower Q.
C . Use 10 Ohm inductor because it has a higher Q Q wL/R where w is the frequency in radians per second, L the inductance and R the resistance of the inductor.
You need the higher Q !!! . - Q being defined as the ratio between the inductive reactance XL ω*L and the resistance R - ω (in radians per second) equates 2 times PI multiplied by frequency The higher the Q, the lower the resistance.that's why correct answer is C)
