Lightning Strike and electrical power surge

AI Thread Summary
A lightning strike near the home caused significant damage to a wired and wireless computer setup, affecting the modem, router, and a NIC card. The wired computer lost its modem and router, while the wireless computer suffered extensive damage to its NIC card and surround sound system. Despite both computers being connected to surge protectors, the wireless computer experienced severe damage, raising questions about the nature of the electrical surge. The discussion suggests that the surge may have traveled through the internet cable rather than the power supply. Overall, the incident highlights the unpredictable effects of lightning on electronic devices and the limitations of surge protection.

Recently, lightning hit near my home (as best as I could tell, not my home directly) and caused considerable damage to my home computer. I have a wireless network with 2 desktops...one direct wired using ethernet cable and the other using a NIC card. When the lightning struck, my wired computer lost the modem, the router, and that was it! My wireless computer lost the NIC card (it was blasted into many pieces inside the tower) and my surround sound speaker system. Both CPUs seem fine...and really all other components in the house are fine. I'm thinking the CATV line got struck and surged into the modem and router. BUT WHY DID THE WIRELESS CONNECTED COMPUTER HAVE DAMAGE, ESPECIALLY THE NIC CARD BEING BLASTED APART? Just wondering what was going there? Any insight would be greatly appreciated!

The computer's internet connection was wireless, right? I mean, was it plugged into the power source in the wall?
 
Both computers (gateway and remote) were plugged into surge protection power strips.
 
Sorry for digging it up. I would also like to know the answer to this one.
 
After several conversations with numerous electricians and academic professionals, I've yet to ascertain a definitive answer as to the occurrence of the electrical surge!
 
Hi CM

You were using NIC to connect the two computers. If there was no damage to the motherboards, then that would mean that the problem happened with the internet cable carrying the signals.
 
Susskind (in The Theoretical Minimum, volume 1, pages 203-205) writes the Lagrangian for the magnetic field as ##L=\frac m 2(\dot x^2+\dot y^2 + \dot z^2)+ \frac e c (\dot x A_x +\dot y A_y +\dot z A_z)## and then calculates ##\dot p_x =ma_x + \frac e c \frac d {dt} A_x=ma_x + \frac e c(\frac {\partial A_x} {\partial x}\dot x + \frac {\partial A_x} {\partial y}\dot y + \frac {\partial A_x} {\partial z}\dot z)##. I have problems with the last step. I might have written ##\frac {dA_x} {dt}...
Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'
I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
