与精灵有关的电荷和电流系统构成了大规模大气电路的一部分，为物理理解最近发现的源自精灵体内流动的电流的极低频辐射提供了一个背景。结果表明，在闪电产生的暂态准静电场的驱动下，精灵导体中的电流脉冲在极低频范围内产生了与引起闪电放电辐射相当的电磁辐射。
Charge and current systems associated with sprites constitute a part of the large scale atmospheric electric circuit, providing a context for physical understanding of recently discovered ELF radiation originating from currents flowing within the body of sprites. It is shown that the impulse of the electric current driven in the conducting body of the sprite by lightning generated transient quasi‐electrostatic fields produces significant electromagnetic radiation in the ELF range of frequencies, comparable to that radiated by the causative lightning discharge.
