admittal 

MILITARY - A formal, professional disclosure or confession provided in the interest of integrity and transparency, admitting to having made a mistake or engaged in acts of misconduct in one's past.

In order to enlist in the United States Army, I was compelled to formally submit a "self admittal" up the chain of command explaining in detail every law enforcement encounter I had in my past, and why I still believed it would be in the Army's best interests to consider me for enlistment and acceptance dispite my criminal background discrepancies.

admittance 

The inverse of impedance. Usually denoted as "Y" in electrical equations, or 1/Z, Z being impedance. The unit value of admittance is commonly dubbed "mhos" (backwards spelling of ohms.) It is a measure of the lack of impedance in a circuit, system of circuits or a specific conductor. A short circuit should, ideally, have an admittance of infinity. An open circuit will have an ideal admittance of 0 mhos.

Z = 10 ohms
Y = 1/Z = 1/10 = 0.1 mhos

Student 1: What's admittance?
Student 2: I don't know. I just use 1/Z.
Student 1: Oh ok.
