Question

where we use platinum wires

Answer 1

Explanation:

Platinum and its alloys are used in surgical tools, laboratory utensils, electrical resistance wires and electrical contact points.

Answer 2

Answer:

Platinum wire is useful for making an electrical connection in a sealed glass system, as it has approximately the same rate of thermal expansion as glass and will seal well with molten glass. It was widely used in early electric bulbs and radio tubes for this purpose, but was quickly abandoned when lower cost materials such as Dumet were developed.
