こういう、発電所とコイルの巻数的な問題での消費電力はRI^2と表しがちなのでしょうか？VIではダメなのでしょうか？この問題(4)では、VIとして解こうとしても解けません…

129 空欄に入る数値を, 解答群から選べ。 同じものを繰り返し選んでも よい｡ 発電所で発電された交流の電気は,変圧器(トランス) により電圧を高 くして, 送電線を通して送られる。 たとえば,電圧を10倍にするには

このときの、C2に溜まる電気量、かかる電圧って求められますか？

この問題の(3)を解くにあたって、 「ACDの電位降下=ABCDの電位降下」ということを知らないと解けないらしいのですが、 これは「スタートとゴールが一致してれば (任意の点)から(他の任意の点)までの電位降下は等しい」ということですか？それとも今回のAとDのような、起電力... Read More
