Question

25、如圖，電阻箱兩接線(xiàn)柱間的電阻值是

8678

Ω．

Answer 1

分析：根據(jù)對(duì)應(yīng)的倍數(shù)的指針?biāo)鶎?duì)的數(shù)字讀數(shù)．

解答：解：×1000的位置對(duì)應(yīng)的數(shù)是8，×100的位置對(duì)應(yīng)的數(shù)是6，×10的位置對(duì)應(yīng)的數(shù)是7，×1的位置對(duì)應(yīng)的數(shù)是8，故是8678Ω．
故本題答案為：8678．

點(diǎn)評(píng)：本題考查了電阻箱的讀數(shù)方法：把對(duì)應(yīng)的數(shù)位上的數(shù)字讀出，按照數(shù)位寫(xiě)出即可．
