Application +4 | -1
In an LCRL C R circuit, the resonating frequency is 200  kHz\,{kHz}. If the value of LL is doubled and value of CC is decreased to 18\frac{1}{8} times of its initial values, then the new resonating frequency in kHz{kHz} will be
View answer and explanation
Correct option: A
400
Option A (400 kHz) is correct because the resonating frequency is inversely proportional to the square root of the product of inductance and capacitance.
