32. The world's first battery was made by $\qquad$ in 1800 using different metals in contact with an electrolyte to form an electric pile.
A. Ohm
B. Ampère
C. Volta
D. Volt
【Answer】C
【Analysis】As early as in ancient times, there were devices similar to today's batteries, but the first recognized battery was the Voltaic Pile invented by Italian scientist Volta in 1800, using different metals in contact with an electrolyte. The invention of the Voltaic Pile provided a method for obtaining a stable and continuous current, marking the transition of electrical studies from static electricity to dynamic electricity. This had profound implications for the study of electricity, deepening the understanding of the relationships between light, heat, electromagnetism, and chemical changes, leading to a series of significant scientific discoveries related to electrochemistry and electromagnetism, and opening up broad prospects for the application of electricity. In memory of this physicist, the unit of voltage was defined as Volt (missing the letter a), pronounced as Volt. Note that the name Volta is pronounced as Volta, and the unit name Volt is pronounced as Volt.
