Bipolar junction transistor quiz: 3 questions

Three questions on the Bipolar junction transistor card, the way WikiCards duels ask them. Pick an answer, the facts are just below.

  1. Find the missing word

    In contrast, a ______ transistor, such as a field-effect transistor, uses only one kind of charge carrier.

    Answer

    unipolar. In contrast, a unipolar transistor, such as a field-effect transistor, uses only one kind of charge carrier. From the Bipolar junction transistor article on Wikipedia.

  2. Which of these cards hits hardest (highest ATK)?

    Answer

    Valparaíso. Valparaíso 84 · Bipolar junction transistor 77 · Metallurgy 74 · Wilhelm Röntgen 70 ATK in WikiCards.

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.

Why it is Uncommon

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Bipolar junction transistor article was read about 130,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 77 and blocks with 71: each hit it takes is cut by 28 %.

How to get Bipolar junction transistor

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.
