what is the electrical conductivity of brass, aluminium, mild steel and air?

The value should be in siemens?

please reply.

Google this question, don't waste our time with your homework

Start with the definition of "siemens".

Look it up: Kempe's Engineers' Yearbook, any edition.

Oh, and the units of conductivity are siemens/cm, BTW.

Oh, and air is an insulator, so it doesn't have a conductivity. Only a break-down voltage gradient. Above that figure it ionises, and its electrical properties are a function of temperature, pressure, moisture content, dirt content, etc., etc.
