[題目]
Two uniform wires, X and Y, each of length 1.0m are connected in series to a
battery of emf 12.0V. The resistance of X and Y are 8.0 ohm and 4.0 ohm
respectively.
Please sketch the E-x graph. x is the distance from the positive terminal
of the battery
[瓶頸]
在wire 內, E-field strength 應隨著離+極距離 而減少???
跟drift velocity 會有關係嗎?
