Amount of electrical energy converted to heat energy when current flows through a conducting material.
According to Joule's Law, quantity of heat energy dissipated is given by,
Q=i2Rt
note- in power transmission, aluminum wires* are used to reduce the heat energy loss
- using a step up transformer,we increase the voltage and reduced in current to reduce heat loss.(heat loss is proportional to the square of current.)
* though silver is the material with minimum resistance,it is too dear to be used as transmission wires.

Is conductors of heat and conductors of electricity the same thing?
Sometimes. Metals will conduct both heat and electricity. Glass will conduct heat but not electricity.
Is radon a good conductor of electricity and heat?
Refer to the periodic table of elements and check if radon is a metal or not. If it is a metal then it will be good conductor of heat and electricity. If it is a gas it will not be good conductor of heat and electricity
What is always present when there is electricity?
heat
Is physical property ability to transfer heat or electricity easily?
Yes, the ability to transfer heat or electricity easily is classified as a physical property. Materials that conduct heat well are known as thermal conductors, while those that allow electricity to flow easily are termed electrical conductors. Metals like copper and aluminum are examples of good conductors for both heat and electricity. In contrast, insulators are materials that resist the transfer of heat or electricity.
Is heat is a form of electricity?

Can solar heat conduct electricity?
yes solar heat can conduct electricity
Is calcium a good conductor of electricity and heat?
Yes, calcium is a good conductor of heat and electricity. Most metals are good conductors of heat and electricity. Most nonmetals are not good conductors of heat and electricity.
