P=IE
power(heat) = current * voltage
or P=I*I*R
yes,joule is a heating reversible effect .
how would you show the heating effect of a current?
No, heating and cooling does not effect the strength of a glass
By heating the density is lowered.
BY reducing the resistances of the circuit, By using Maximum transfer theorem and Joule's law. Copper wires are better conductors than, for instance, than aluminum wires. After insulation, I placed the circuit in water to keep it from overheating (big heat sink).
No, all resistances in series connections are not the same. Different value resistances can be series together. The results of the resistances in series are always the same, they are additive.
by the radiation in the filament it throw out heat . this way the bulb demonstrates the heating effect. :D
Heating effect
No, because heating matter does not effect the mass.
The heating effect of electric current was discovered by James Prescott Joule in the mid-19th century. Joule's experiments showed that the temperature of a conductor increases when an electric current passes through it.

Infrared radiation from the sun produces a heating effect on the Earth's surface. This radiation is responsible for warming the planet and heating objects on the surface.
