Which is an example of a voltaic cell?

a battery

electrolysis of water

electroplating of chrome

a rechargeable battery

Out of the given choices, a battery is an example of a voltaic cell.

A voltaic cell, also referred to as a galvanic cell, relies on a spontaneous redox reaction to create a potential difference, and a subsequent flow of electrical charges. The electrons flow from the anode to the cathode in a voltaic cell.

The answer here is A!
