A chemical process.
It's a chemical change. A thin layer of silver on the surface reacts with oxygen in the air - to form silver oxide.
The tarnishing of silver is due to a reaction with hydrogen sulfide. Because the end result of the tarnish is silver sulfide, it is a chemical change.
Conductivty is an electrical property of conducting materials. Silver has the higest conductivity, then copper then aluminimum. Conductivity does not really change with electrical wiring so the power will not be directly affected.
Silver invented Post-It Notes. He was trained as a chemist.
Silver is used as a low resistance conductive material. Contactors and relays contact points are made of copper and are silver plated to obtain the lowest resistance between the moving contact faces.
It is a chemical change.

Tarnishing is actually oxidation of the silver, so it would be a chemical change.

Silver platter tarnishing is a chemical change: a reaction with hydrogen sulfide.
It's a chemical change. The silver reacts with sulfur compounds from the air.
