在导电纸中通均匀直流电流模拟匀强电场,以一定距离选取基准点,用灵敏电流计寻找等势点,进而描绘得到了等势线。测量了相邻等势线间的电势差,计算得出电势差与间距的比值近似与理论数值相等。
In the conductive paper through the uniform DC current simulation uniform electric field to a certain distance to select the reference point, with sensitive galvanometer looking for potential points, and then described the equipotential line. The potential difference between adjacent equipotential lines was measured and the ratio of the potential difference to the pitch was calculated to be approximately equal to the theoretical value.
