In the December 2008 issue of EC&M, we talked about calculating the inductive reactance of conductors that are in close proximity to (or touching) one another. We also noted that the inductance and, ...

Resonance As with series circuits containing resistances, inductances, and capacitances, if the inductive reactance of a parallel circuit equals the capacitive reactance, the circuit is said to be ...

So now we have: Impedance = Resistance + Inductive Reactance – Capacitive Reactance, but even this formula is an over-simplification because the reactance is dependent on the frequency of the current ...

As you can see, the inductive reactance increases with frequency, just the opposite of capacitive reactance. Connecting two coils/inductors in series gives you a larger inductor, just add the two ...
