Method to solve this?

Hima said:   1 decade ago
F = 1 / 2πsqrt(C (L1 + L2 ))

Raz said:   1 decade ago
f = 2*3.14sqrt((200*10-9)(60*10-3)).

Please solve answer.

Ajay said:   1 decade ago
F = 2 x 3.14 sqrt((200 x 10-9)(60 x 10-3).

Please more explain is square root, 10-9 and 10-3.

F = 1/{2φsqrt(C (L1 + L2 ))}.
F = 1/{2 x 3.14 sqrt((200 x 10 - 9)(60 x 10 - 3)}.
F = 1/{2 x 3.14 sqrt(12 x 10 - 9)}.
F = 1/{2 x 3.14 x 3.46 x 10 - 3}.
F = 1/{21.75 x 10 - 3}.
F = 45.97.

I thought the two inductors were in parallel due to ground :( .
