Question 1:

Use the formula for the self-resonance frequency to calculate the value for the turn-to-turn parasitic capacitance of the inductor used in your experimental setup.

Answer 1:

The value of the turn-to-turn parasitic capacitance of the inductor used in the experimental setup can be computed as follows:

Given the values:

L = 100 μH

f_SR = 5 MHz

We obtain the value of C_parasitic ≈ 1.275 × 10⁻¹⁵ F ≈ 1.275 fF.
