Inductor/Resistor/Capacitor Equivalency

[Monty Hall]

Hello,

I'm a Chemical Engineer that took an "Electrical Engineering for
Non-Electrical Engineers" class as part of my degree ~7 years ago. I was
wondering if somebody can reconstruct my failing memory when I recalled my
instructor saying something to the effect that "For a resistor, inductor,
capacitor, one can be simulated by the other two" I don't recall in what
context he was speaking - or if I'm recalling it correctly. It definetly
had something to do w/ interchangeability. Can somebody direct me to a text
or website concerning this matter?

Regards,

Monty,

Nope, can't simulate an inductor using a resistor and capacitor.
Use a capacitor and an operational amplifier?

Perhaps he meant that you can construct a single-stage lowpass filter
using either an inductor *or* a capacitor, plus a resistor. Same is
true for hipass.

Nope! Can't be done iMHO, whichever way you look at it.

Hi.
In an alternating current context, a resistive value R can be obtained
as capacitive reactance Xc=R or by inductive reactance XL=R.
XL = 2śfL
Xc = 1÷2śfC
In resonant circuits, capacitors and inductors together (in series or
parallel) can also yield a resistive value equal to R from a resistor.

Maybe that is what you mean.
