Question

Mr Nayan and mercury which is better conductor of electricity and why

Answer 1

both are best conductors

iron is the best conductor of electricity

mercury is the best conductor of heat

Answer 2

the resistivity value of iron and mercury are 10*10 power-8 ohm and 94*10 power-8 ohm respectively.

listen one thing the conductivity of any material is proportional to 1/respectively so conductivity=1/resistivity

therefore, if you put the value in eqation you find iron as better conductivity than mercury so, it is a better conductor
