An $L . C . R$ circuit contains $R = 50 Ω, L = 1 mH$ and $C = 0. 1 μF$ . The impedance of the circuit will be minimum for a frequency of

Options:

Answer:

Solution:

The impedance of L-C-R circuit will be minimum for a resonant frequency so,

$v_{0} = \frac{1}{2 π \sqrt{L C}}$

$= \frac{1}{2 π \sqrt{1 \times 10^{- 3} \times 0.1 \times 10^{- 6}}}$

$= \frac{10^{5}}{2 π} Hz$
