In what situation would eigenVolts be a valid unit?
Maybe Eigen Volts, eigen volts, Eigenvolts, or what have you. Unit-term capitalization plays fast and loose with rules. But whatever.
If you have a matrix of potentials, you might be able to address the matrix eigenvalues as eigenvolts, but you wouldn’t do that addressing the value itself. An eigenvalue of 2.3V would just be 2.3V. To meaningfully use a term eigenvolts, you’d have to….what? Be describing potential degeneracy?
There should be a situation wherein eigenvolts would be useful, but I can’t think of one.
