Question

Show an activity to prove that metals are good conductor of electricity

Answer 1

Well its simple most of the metals are good conductors. We can take silver, copper, aluminum, iron etc. Not all metals are good conductorsof electricity and heat. In one example, titanium alloy Ti-6Al-4V has a thermal conductivity of 5.8W/m-K and in another stainless steel as low as 17W/m-K.
