JEE PYQ: Alternating Current Question 15
Question 15 - 2021 (25 Feb Shift 1)
A transmitting station releases waves of wavelength 960 m. A capacitor of $256\mu$F is used in the resonant circuit. The self inductance of coil necessary for resonance is ____ $\times 10^{-8}$ H.
Show Answer
Answer: 10
Solution
At resonance, $L = \frac{\lambda^2}{4\pi^2 c^2 C} = 10 \times 10^{-8}$ H.
