学习完欧姆定律后,爱动脑筋的小明看到爸爸正在修理家里的电视机,经检查是一只电阻器被烧坏,他发现爸爸换下来电阻器的铭牌已经很模糊。小明和爸爸说:“我能利用我学过的知识知道这个电阻的阻值多少。”爸爸很高兴地的说:“那这个问题就由你来解决了。”
After learning Ohm's law, the brainy Xiaoming saw that Dad was repairing the television in his home. After checking that one of the resistors had been burned out, he found out that his nameplate had been obscured by his father's replacement of the resistor. Xiaoming and Daddy said: “I can use the knowledge I've learned to know how much resistance this resistance has.” “Daddy said happily:” That's the problem for you. “”
