And finally, not even a full lightning protection system with rods, cables and grounds will guarantee against damage to electronics and computers. For any system to provide 100% protection, it must divert almost 100% of the lightning current from a direct strike, which is nearly physically impossible: Ohm's Law states that for a set of resistances connected in parallel, the current will be distributed across ALL resistances, at levels inversely proportional to the different values of resistance. A house or building is nothing more than a set of resistors 'connected' in parallel—the electrical wiring, plumbing, phone lines, steel framework, etc. (Even though plumbing and electrical wiring, for instance, may not be physically connected, lightning will use side flashes across air gaps to effectively connect them). In a direct lightning strike, the current will not follow only one path—it will distribute itself across all paths to ground depending on each path's resistance. From West Virginia Lightning
Let's end with some interesting history on the subject:
