Previous Year NEET Question- Lc Oscillations
- 2019:
The given values are:
- R = 20 Ω
- L = 1.5 H
- C = 35 μF
- V = 220 V
- f = 100 Hz
The formula for Q factor is:
Q = \frac{1}{R}\sqrt{\frac{L}{C}}
Substituting the given values, we get:
Q = \frac{1}{20}\sqrt{\frac{1.5}{35 \times 10^{-6}}} = 24.6
Therefore, the Q factor at this frequency is 24.6.
- 2018:
The formula for resonant frequency is:
f_r = \frac{1}{2\pi \sqrt{LC}}
Substituting the given values, we get:
f_r = \frac{1}{2\pi \sqrt{1.5 \times 10^{-3} \times 35 \times 10^{-6
