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 metal a poor conductor of heat and electricity?
No, metal is a good conductor of both heat and electricity. Metals have a high density of free electrons that can move easily and carry heat and electrical charge efficiently. This is why metals are commonly used in applications where good conductivity is required.
