Ohm's law, a Rare card
Ohm's law states that in a well-behaved conductor, the electric current between two points is directly proportional to the voltage across the two points.

Ohm's law quiz: 3 questions
Three questions on the Ohm's law card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
More specifically, Ohm's law states that the R in this relation is constant, independent of the ______.
Answer
current. More specifically, Ohm's law states that the R in this relation is constant, independent of the current. From the Ohm's law article on Wikipedia.
Which of these cards hits hardest (highest ATK)?
Answer
List of mayors of New York City. List of mayors of New York City 83 · Physicians in Canada 79 · Ohm's law 76 · Battle of Hattin 72 ATK in WikiCards.
Which of these Wikipedia articles is read the most in a year?
Answer
Wiki. Wiki 4,900,000 · Ohm's law 350,000 · Visa requirements for Honduran citizens 11,000 · Physicians in Canada 3,000 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- Introducing the constant of proportionality, the resistance, one arrives at the following mathematical equation used to describe this relationship: V = I R or, equivalently, at the same equation expressed in terms of the reciprocal constant of proportionality, the electrical conductance, I = G V where I is the current through the conductor, V is the voltage measured across the conductor, R is the…
- More specifically, Ohm's law states that the R in this relation is constant, independent of the current.
- If the resistance is not constant, the previous equation cannot be called Ohm's law, but it can still be used as a definition of static/DC resistance.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Ohm's law article was read about 350,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 76 and blocks with 74: each hit it takes is cut by 30 %.
How to get Ohm's law
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.
