What's the difference between admittance and impedance?

Admittance


Definition:

  • (n.) The act of admitting.
  • (n.) Permission to enter; the power or right of entrance; also, actual entrance; reception.
  • (n.) Concession; admission; allowance; as, the admittance of an argument.
  • (n.) Admissibility.
  • (n.) The act of giving possession of a copyhold estate.

Example Sentences:

Impedance

Example Sentences:
