What happens to an electric charge which a lightning rod receives from a strike?

Lightning is caused by electrons building up, either in the ground or in the clouds. When this electric potential becomes greater than the dielectric strength of the air between ground and clouds, the electrons will flow from one to another in the form of lightning. The dielectric strength of air is directly related to the distance between the two objects of interest. A lightning rod works by being higher than whatever it is meant to protect, so as electrons build up, lightning will strike the rod instead of whatever it is protecting. The lightning rod provides a low impedance path to ground, acting as a drain for the electrical build up.
So it attracts lightning by being higher than whatever it is protecting; it also discharges the electrical potential by providing a low impedance path to ground.

∙ 11y agoSince Ben Franklin invented the lightning rod by using a kite & a key,if lightning strikes a lightning rod,the electricity will travel through the rod,then powers the house.

How high is a bolt of lightning?
Davidmt1:Lightning is never the same height. This is because some clouds can be lower than others. Also there are two type of lighning. There is cloud to ground lightning and cloud to cloud lightning.
Do people who have been struck by lightning carry an electrical charge and can they be touched?
People who have been struck by Lightning does not carry a residual charge. Lightning goes straight through the body and into the ground. There would be no electrical charge left and they would be safe to touch.
What is ligthing?
ž žLightning is caused by the build up of electrostatic charge in clouds Lightning is caused by the build up of electrostatic charge in clouds
Is electric field dependent of magnitude of charge?
Electric field is dependent on the magnitude of the electric charge, E = qzc/r2
How is lightning produced in the clouds if there is water in them?
Lightning is the discharge of static electricity. Items on the ground, including the ground itself, has one charge while the clouds in the sky, even the sky itself has the opposite charge. When one has more charge than the other, it discharges causing lightning.
How is electricity different from other electricity?
Static electricity is electric charge just sitting there. Electric Current is electric charge in motion. And the original terms for electricity is Lightning, Thunderbolt.
What happens when water flows over plexiglass electric charge?
Yup, an electric charge is generated.
What happens to its mass if the object receives a negative charge?
Practically nothing
Ball A has a charge of 3 Coulombs Ball B has a charge of 5 Coulombs What is the net electric charge?
5 COLOUMBS?!?!?!?!?!?!?!?!!?!??!?!?! That is a lot of lightning
What happens before there is a lightning discharge?
The cloud's strong negative charge attracts the ground's positive charge
How powerful is bolt of lightning?
An average bolt of negative lightning carries an electric current of 30,000 amperes (30 kA), and transfers 15 coulombs of electric charge and 500 megajoules of energy.Positive lightning strikes typically carry six to ten times the charge and voltage difference of a negative bolt.
When is lightning most likely to happen?
lightning mostly happens when there are a lot of clouds in the sky because lightning is the result when ice particles with negative charge is rubbed with another ice particle but with positive charge.
Is electric charge a tiny amount of energy?
Depends on the amount of the electric charge and on which place it is stored. Two clouds with a big amount of a potential electric charge, one positive and the other negative, will produce a huge amount of energy represented by a lightning bolt.
What are some real life examples of electric charge?
Static electricity, lightning, and the electricity used to power appliances are all electric charges.
What charge does lightning have?
Lightning has an negative charge
Is it dangerous to play the piano when there is lightning?
Only if you are playing it outside. It has no electric charge. However, if you are going to shower whem there is lightning, you are in more danger moreso if you are playing a piano.
Why lightning cannot occur in vacuum?
What you see as lightning is air that has been superheated until it glows by an electric charge travelling through it. In a vacuum there is no air, thus no visual.
