Question

The following table gives the resistivity of: A B C Resistivity
1 6x10^-8, 5 2x10^-8 and 100x10^-6 ohm meter Which of these is
suitable for making heating elements of electrical appliances and
why?

Ajay Shukla · Accepted Answer

Higher will be the resistivity higher, will be its resistance
and more will be the heating as heating is directly proportional to
R according to joule heat law Thus C is better choice

The following table gives the resistivity of: A B C Resistivity 1.6x10^-8, 5.2x10^-8 and 100x10^-6 ohm meter. Which of these is suitable for making heating elements of electrical appliances and why?
