The facts on the card
The card carries these facts from its Wikipedia article.
- One ampere is equal to 1 coulomb moving past a point per second.
- It is named after French mathematician and physicist André-Marie Ampère, considered the father of electromagnetism along with Danish physicist Hans Christian Ørsted.
- As of the 2019 revision of the SI, the ampere is defined by fixing the elementary charge e to be exactly 1.602176634×10−19 C, which means an ampere is an electric current equivalent to 1019 elementary charges moving every 1.602176634 seconds, or approximately 6.241509074×1018 elementary charges moving in a second.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Ampere article was read about 210,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 62 and blocks with 36: each hit it takes is cut by 14 %.
How to get Ampere
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
