What will be the oscillator frequency of Hartley oscillator if inductance L1, L2 are equal to 1mH and 2mH respectively and capacitor C is 10nF. (Neglect mutual inductance)

What will be the oscillator frequency of Hartley oscillator if inductance L1, L2 are equal to 1mH and 2mH respectively and capacitor C is 10nF. (Neglect mutual inductance) Correct Answer 29KHz

L1 = 1mH L2 = 2mH Effective inductance L = L1+L2 = 1+2 = 3mH C = 10nF Oscillator frequency . Frequency = 29kHz.
