The facts on the card
The card carries these facts from its Wikipedia article.
- An example of a galvanic cell consists of two different metals, each immersed in separate beakers containing their respective metal ions in solution that are connected by a salt bridge or separated by a porous membrane.
- Volta is the inventor of the voltaic pile, the first electrical battery.
- Common usage of the word battery has evolved to include a single galvanic cell, but the first batteries had many galvanic cells.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Galvanic cell article was read about 65,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 65 and blocks with 35: each hit it takes is cut by 14 %.
