# If we connect 3 coils with same inductance in parallel will the resonant frequency of the circuit be as if there is just 1 coil with 1/3 ind?

Update:

We are ignoring the capacitance just to make the point.

Update 2:

I know inductance is 1/3, i asked about resonant frequency.

Resonant frequency is inversely proportional to the square root of the product of L and C. If C remains constant and L drops to 1/3, then the resonant frequency increases to √3 = 1.732 of the original.

Total inductance will be 1/3. Example, three 3.6mH inductors in parallel gives you 1.2mH.

Just like resistors in parallel.

This is the same answer you got last week.
