An $L - C - R$ circuit contains $R = 50Ω, L = 1 mH$ and $C = 0.1 μ F$ . The impedence of the circuit will be minimum for a frequency of

Options:

Answer:

Solution:

Impedance of L-C-R circuit will be minimum for a resonant frequency so, $= v_{0} = \frac{1}{2 π L C} \frac{1}{2 π 1 \times 1 0 ^{- 3} \times 0.1 \times 1 0 ^{- 6}} = \frac{1 0 ^{5}}{2 π} Hz$
