Topic: Electronics Engineering
A coil has self resistance of $5~\Omega$ and inductance of $1~\mu H$. The value of Q at 1 MHz frequency is
- A. 200
- B. 100
- C. 40
- D. None of these
Answer: D. None of these
Explanation: $Q=\frac{\omega L}{R}=\frac{2\pi fL}{R} = \frac{2\pi\times1\times10^{6}\times1\times10^{-6}}{5}=1.2566$
