1. Electrostatic induction, that is, the change of the ground atmospheric electrostatic field caused by lightning, which causes the conductors near the lightning-connected object to generate induced charges, forming a very high potential difference to the ground;
2. Electromagnetic induction, that is, the current in the lightning channel changes with time, forming a changing electromagnetic field in the space around it, and generating induced voltage and eddy current on the conductive objects attached to the channel;
3. Electromagnetic radiation, which is formed by the rapid change of the current in the lightning channel. Since the electronic truck scale can only withstand low voltage, the above three physical processes caused by lightning are destructive to it, especially electromagnetic induction. The more sophisticated, less power-hungry, and more sensitive microelectronic devices are, the more destructive they are.
