What are disadvantages of static electricity?
Static electricity can also cause uncomfortable shocks to a person who becomes "charged up". To experience this shock, drag your feet across a carpet in socks, then touch your finger to a doorknob. Static electricity can be responsible for the ignition of flammable gases, such as the vapors produced by petrol (gasoline) when you are filling your car.
Well i don't know about electricity but i know about static electricity. Lightning is like static electricity, except on a much bigger scale. Both lightning and static electricity happen because of the attraction between the opposite charges. When static electricity moves, it is a current. When static electricity in clouds discharges to earth there is a huge, very short current pulse (surge).
