When no current flows in a stationary conductor, the continual orbiting and jostling of these particles lead to no resultant large-scale movement of either positive or negative charge one way or another. If an electric cell is connected in a closed circuit of conductors, the cell tends to ...
Current without potential difference 电路短路时,电池正极和负极之间的电位差虽然在理想情况下应该接近于0,但在实际情况下仍然会有一些电位差存在。这些电位差和电流的产生有几个主要原因: 1. 电池内阻 电池并不是一个理想的电源,它具有内阻。当电池短路时,电流会通过电池的内阻产生一个小的电位差。这就解释了为什...
