The electric current obtained from galvanic cell is a result of electrons being pushed forced from the negative electrode, through an external wire, to positive electrode. The force with which these electrons move through the wire is called:
Correct answer: D. Both A and C
- A. Electromotive force (Emf)
- B. Electrode potential
- C. Cell potential
- D. Both A and C
Explanation
The correct answer is 'Both A and C' because 'Electromotive force' (Emf) and 'Cell potential' are related concepts. Emf is the maximum potential energy per unit charge provided by the cell to drive the current, while cell potential refers to the specific potential difference between the electrodes that drives the flow of electrons from the anode to the cathode in a galvanic cell. 'Electrode potential' is incorrect as it pertains to the potential of an individual electrode, not the driving force for the entire cell.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
