Voltaic cell can be recharged by
Correct answer: B. replacing external circuit with external source of electricity
- A. by addition of fresh solution
- B. replacing external circuit with external source of electricity
- C. by removal of solution
- D. by heating it
Explanation
Voltaic cells, also known as galvanic cells, convert chemical energy into electrical energy. These cells can be recharged by reversing the current flow using an external source of electricity, driving the non-spontaneous reaction backward and replenishing the reactants.

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.
