Why does an inductor behave as a capacitor at high frequencies?
In truth, I''ve only been told this anecdotally by an instructor, but can someone explain the physics at play? I have been told that if an inductor is driven at a high enough frequency, it will begin to behave as an capacitor, but I cannot figure out why.
Capacitors | Brilliant Math & Science Wiki
14 · Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured …
