A charged 30 muF capacitor is connected to a 27 mH inductor. What is the angular freuqency of free oscillations of the circuit? |

Answer» Solution :For free LC oscillations, `omega = ( 1)/( sqrt( LC))` ` = ( 1)/( sqrt(27 xx 10^(-3) xx 30 xx 10^(-6)))` `= (1)/(sqrt(81 xx 10^(-8)))` `= ( 10000)/( 9)` `= 1111 ( rad)/(s)` `= 1.111 xx 10^(3) ( rad )/(s)` |
