We're getting close! Yes, a capacitor can be made to store some of the charge from a lightning strike. Early experimenters with electricity back when both capacitance and lightning were poorly understood used something called a "Leyden jar". It was meant to be a bottle for electric charge.
Blunt-tipped lightning rods have been found to be more receptive to lightning strikes and thus provide a more likely path of discharge of a charged cloud. When installing a lightning rod on a building as a lightning protection measure, it is imperative that the rod be elevated above the building and connected by a low resistance wire to the ground.
Furthermore, recent field studies have further shown that the tip of the lightning rod does not need to be sharply pointed as Ben Franklin suggested. Blunt-tipped lightning rods have been found to be more receptive to lightning strikes and thus provide a more likely path of discharge of a charged cloud.
That's good for 0.01 C. An average lightning strike has a 5 C charge, so the capacitor won't survive it; the voltage will rise to 50 MV, destroying the capacitor. In the same article it says that a positive lightning bolt has 100 times more charge, and then you're better not near the capacitor when it gets hit.
I was always under the impression that a Lightning rod worked to protect a building by being the tallest part of the building and having a low path of resistance to the ground, thus being a good target for lightning to hit, reducing the chances of lightning strikes elsewhere on the building.
However, this affect only extends for a few meters above the tip of the lightning rod. A few meters of enhanced conductivity above the tip of the rod is not capable of discharging a large cloud that stretches over several kilometers of distance.
The amount of storage in a capacitor is determined by a property called capacitance, which you will learn more about a bit later in this section. Capacitors have …
In order to prevent step voltage from harming people, the distance of lightning rod grounding devices from buildings, structures entrances and sidewalks should not be less than 3m. The …
However, installing lightning rods is absolutely not a DIY project. Get it wrong and a lightning rod can become a danger instead of offering protection. In other words, this is …

The amount of storage in a capacitor is determined by a property called capacitance, which you will learn more about a bit later in this section. Capacitors have applications ranging from filtering static from radio …
Lightning can "jump around" when it strikes.This "jumping" is associated with the electrical potential of the strike target with respect to the ground''s potential. The lightning can …
direct strike by lightning conductors and ground rods as shown in figure 1. The conductor carries the very large strike current into the earth termination and dissipates the charge transfer into …
To start with, attracting a lightning bolt would take much more sophisticated equipment than an iron key at the end of a silk string. Tall metallic rods extending high above …
When it was a few dozen meters from ground level, lightning rods and tall objects on the tops of nearby buildings produced positive upward discharges, competing to connect to the downward strike. The final image …
capacitors in parallel: that means the wires from the two top plates are joined, similarly at the bottom, so effectively they become one capacitor. • What is its capacitance? From the picture, …
