Specification
Material: metal/plastic
Characteristics
During the experiment, the water in the graduated cylinder should not be too much, and the metal cylinder should be leaked out of the water surface. The volume of the metal object is not easy to be small, so the experiment effect is better.
The heating wire is a nickel wire, the resistance value is 2 ohms and 1 ohms, and the working current is 1.7A-2A.
Suitable for physics teaching experiment demonstration, determination of specific heat of objects, determination of electrothermal equivalent.
