The cover of the electric calorimeter contains a mounted heating coil of about 1.5 ohms resistance with standard binding posts for electrical connections. When connected to a 6-volt battery, this coil will cause a temperature rise of about 5 degrees centigrade in 10 minutes. The unit is designed to help students determine the electrical equivalent of heat. The supporting posts and coil are coated to prevent electrolysis. It is provided with an insulated handle, stirrer, and a single-hole rubber stopper.
Battery not included.
