Suppose if I have a toroid core and copper wire is wound around it. So, I want to measure different inductance values of this coil at different frequencies.
Normally we can calculate it by performing open circuit test. However, I am interested in calculating it without using any measurements with only some details.Below is an example of toroid core...
