A transistor - oscillator using a resonant circuit with an inductor L (of negligible resistance) and a capacitor C in series produce oscillations of frequency f. If L is doubled and C is changed to 4C, the frequency will be |

Answer» f/2 or,`(f_(1))/(f_(2))=((L_(2)C_(2))/(L_(1)C_(1)))^(1//2)=((2L XX 4C)/(L xx C))^(1//2)=(8)^(1//2)` `therefore (f_(1))/(f_(2))=2sqrt(2) RARR f_(2)=(f_(1))/(2sqrt(2))` or, `f_(2)=(f)/(2sqrt(2)).(because f_(1)=f)` |
