Which of the following correctly identifies a voltage source and its method of developing electric potential? a. primary cell—heat action on a device b. thermocouple—chemical action c. dry cell—chemical action d. generator—genetic action

Answer;

C. Dry cell—chemical action

Explanation; A dry-cell  stores chemical energy in an immobilized electrolyte paste, which minimizes the need for water.Dry cell batteries create electrical energy by converting chemical energy into electricity. The materials that are used in a dry cell are mostly zinc and carbon or zinc and manganese dioxide. These materials react through a chemical process in which electrolyte reacts with the zinc, thus creating electricity.
