The change in electric potential as a result of lightning in a one-dimensional domain is evaluated. Eigenfunctions are used to evaluate the new potential. The change in the electric potential is a constant along the lightning channel, and it is the same as the pre-flash potential outside the channel. The governing equation for the electric potential is obtained from Maxwell's equations.

模拟一维空间中闪电引起的电势变化

评估一维域中闪电导致的电势变化。特征函数用于评估新的潜力。沿闪电通道的电位变化是一个常数，与通道外的预闪电位相同。电势的控制方程来自麦克斯韦方程。
