Electrical Heat Equivalent (Joule’s Law)

Electrical Heat Equivalent (Joule’s Law)

Equipment:
• Isolated double walled calorimeter made from aluminum.
• Acrylic base with thermal resistance and stirrer.
• DC Power supply (12V/3A).
• Rheostat (25?/3A).
• 2 x Digital multi meters.
• Alcoholic thermometer (0-100?C).
• Cables.
• Digital stop watch.

Product Description

• This experiment used to study the physical meaning of the electrical equivalent of heat, and used to determine it experimentally.
• When electric current pass through resistance, the electric energy is converted into heat.
• Total electrical energy loss W could be easily determined by that law
