Admittance is the process or act of being admitted somewhere. It can also refer to the permission given to enter an area that might be off-limits to the general public or to people who haven’t paid an admission fee.

And here’s why it’s always a good idea to check a couple of sources in any research. The New Penguin English Dictionary (1986) doesn’t mention it, but according to the dictionary bundled with Mac OS/X admittance also has a meaning in physics. It is “a measure of electrical conduction, numerically equal to the reciprocal of the impedance.”

Well, OK.If I remember my math from high school, reciprocal means put one over the number and you’ve got the reciprocal value. So, if I’ve got it right, admittance =\frac {1} {impedance}.

I suppose that makes sense. Conduction refers to the flow of electricity and impedance refers to the resistance to the flow of electricity. So I understand how one would be the inverse of the other. What I want to know is how that gets my toaster oven to work and why the clock on my stove stopped working years ago.
