thermal conductivity is a property describing the material’s ability to conduct heat and is not dependent on the amount of material present.

Explanation:

Thermal conductivity is a physical property of materials that enable heat transmission. This means that when a body has thermal conductivity, heat passes from the body of higher temperature to another of lower temperature that is in direct contact with it.

In other words:

This property implies the ability of a material or substance to transfer the kinetic energy of its molecules to adjacent ones or to other materials (or substances) with which it is in contact.

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes
