Which of the following has the greatest effect in decreasing the oscillation frequency of an LC circuit? Using instead:
A)L/2 and C/2
B)L/2 and 2C
C)2L and C/2
D)2L and 2C
E)none of these

Question

Quizplus · Accepted Answer

The oscillation frequency of an LC circuit is given by 1/(2*pi*sqrt(LC)). As frequency is inversely proportional to the square root of L and C, increasing the values of L and C will result in a decrease in oscillation frequency. Therefore, option D, with both L and C values doubled, will have the greatest effect in decreasing the oscillation frequency.
