解き方がほんとにわからないです

1. 電池の起電力と内部抵抗を調べるために、電池と可変抵抗を図のように 子 する。 はじめ可変抵抗の抵抗を最大にしておき、スイッチを入れ、 [EV[V]と 抗値を少しず [A]を測り、スイッチを切る。 つ小さくしながら同じ測定を繰り返す。 すると図9のような結果が得られた。 V(V) 15.0 10.0 5.0 図 A 0 1.0 2.0 3.0 I(A) 9 wwwwww 4 電池の起電力 E[V) と内部抵抗 (Ω)はそれぞれいくらか。 それぞれの解 群のうちから正しいものを……つずつ選べ。 E- 6 5 の解答群 ① 2.5 ② 5.0 7.5 ④ 10 ⑤ 12.5 15 6 の解答群 10 ② 2.5 5.0 ④ 6.0 ⑤ 10 5 可変抵抗で消費される電力」 P(W) は端子電圧の関数としてどう表され るか。 次の①~④のうちから正しいものを一つ選べ。 0 + V₂ 7 © (E-V)V Ⓒ + Ev +-v 6 電力Pが最大になるのは端子電圧がいくらのときか。次の①~④のう ちから正しいものを一つ選べ。 V= 8 1 0 ④ E 2. 追加 問2抵抗値が R の抵抗二つと起電力がEの電池二つを, 図2の回路(a), (b)の ように接続する。 それぞれの回路で電流計を流れる電流の大きさを1.
