Q.

Hartley oscillator has inductance values of 12 mH and 4 mH in the feedback section and a capacitor of 4 nF. Then the resonant frequency of the circuit is:

A. 19.89 khz
B. 25 khz
C. 45 khz
D. 12 khz
Answer» A. 19.89 khz
Explanation: resonant frequency of hartley oscillator is given by 1/ 2π√(c1 (l1 + l2)). substituting the given values in the above equation, cut-off frequency is 19.89 khz.
