: 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?
Ohm's law 的電磁場形式是 J=sigma*E sigma==>電導率
也就是說在導線內部的電流如果是穩定型態,導縣內電場應該要一致才對
而本題因為是串連,所以電流一定是固定的.故內部電場應該皆相同.
