Electrical Method to Determine Joule’s Constant

 

The difference between electrical and heat energy units is the reason of calculating joule’s constant. Although both of them are the same quantities, one of them is measured in joule units and the other in calorie units.

Equipment list:

  1. Joule calorimeter, the outer part made of compact plastic and the inner part made of glass
  2. Power supply 30 V, 3 A
  3. Alcohol thermometer
  4. Handheld digital chronometer
