Contact plating (finish) provides corrosion protection for base metals and optimizes the mechanical and electrical properties of the contact interfaces.

In electrical engineering, impedance is the opposition to alternating current presented by the combined effect of resistance and reactance in a circuit.

The rate of oscillation of electromagnetic radio waves in the range of 3 kHz to 3 GHz, as well as the alternating currents carrying the radio signals.
