A device converting CHEMICAL energy to electrical energy via spontaneous redox is a:
AHeat engine
BBattery charger
CGalvanic (voltaic) cell
DElectrolytic cell
Answer & Solution
Correct answer: C. Galvanic (voltaic) cell
Galvanic cell (also called voltaic cell, e.g. Daniell cell): spontaneous chemical reaction generates electrical current. Electrolytic cell does the reverse: electrical energy drives a non-spontaneous reaction.
