Question

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, 10 5 2 π Hz, 10 6 2 π Hz, 2 π × 10 5 Hz, 2 π × 10 6 Hz

MARKS App · Accepted Answer

The impedance of L-C-R circuit will be minimum for a resonant frequency so, v 0 = 1 2 π L C = 1 2 π 1 × 10 - 3 × 0.1 × 10 - 6 = 10 5 2 π Hz
