Question

On which factors does Q-factor depend?Answer the given question in brief.

Answer 1

Q factor depends on L, C, R.


Note::-Quality factor decreases with increasing resistance .

Answer 2

Answer:

Q-factor depends on inductance, capacitance, and resistance.  

Explanation:

•  The quality factor for an inductor is defined as the ratio of inductive reactance to the resistance of the inductor at a particular frequency.
• It is used to measure its efficiency.
• The quality factor is expressed by:

                                                 $Q=\frac{1}{R} \sqrt{\frac{L}{C} }$

• Q-factor depends on:

1. $\sqrt{\frac{L}{C} }$ - The value of the Q-factor increases when the value  $\sqrt{\frac{L}{C} }$ increases.
2. R - The value of the Q-factor decreases with an increase in R.

• Q-factor depends on the quality coil also.
• If the quality is good then resistance is less and thus value of the q-factor is more

So, the q-factors mainly depend on the inductance(L), capacitance(C), and resistance(R).
