Question

Find the $Q$ - factor of the circuit given

• A. 0.2
• B. 0.4
• C. 0.6
• D. 0.8

Answer 1

Answer: (C)

$Q=\frac{1}{R}\sqrt{\frac{L}{C}}=\frac{1}{80}\sqrt{\frac{10\times 10^{-3}}{4\times 10^{-6}}}$
$Q=\frac{1}{80}\sqrt{\frac{10\times 10^3}{4}}=\frac{1}{80}\times \frac{10^2}{2}=\frac{100}{160}=0.62$
