In the circuit shown in the figure, the ratio of the quality factor and the band width is _____ ss.

In the circuit shown in the figure, the ratio of the quality factor and the band width is _____ s .

Correct answer

0

Step-by-step solution

In the circuit shown in the figure, the ratio of the quality factor and the band width is _____ s .

For an LCR circuit,

Bandwidth =RL= \dfrac{R}{L}

=103Hz= \dfrac{10}{3}Hz

For an LCR circuit quality factor =LRC= \dfrac{\sqrt{L}}{R\sqrt{C}}

=310×27×10−6=1003= \dfrac{\sqrt{3}}{10 \times \sqrt{27 \times {10}^{- 6}}} = \dfrac{100}{3}

Therefore, required ratio

=10= 10.
