Can electricity exist in a vacuum?
Electricity in a vacuum is quite different than electricity flow in Earth’s atmosphere.
Even at low voltages, electricity can in fact travel through a perfect vacuum.
At low voltages though electrons flow invisible.
A vacuum arc can occur if the electric field is sufficient to cause field electron emission..
Can lightning form in space?
Yes, because charge can flow across vacuum, but no, because you won’t see anything. The visual effect that you see in the sky is actually a luminescent plasma that is left in the wake of the charge moving through the atmosphere. No atmosphere, no plasma, no light.
What state has most lightning strikes?
New research reveals the U.S. states that experienced the most lightning strikes in 2018 – Florida and Texas are at the top of the list. The Sunshine State had the highest density of lightning strikes. Florida had the highest average of negative ground-to-cloud flasher per square mile, with 24, according to the study.
How does lightning look from space?
“Lightning from above,” wrote NASA astronaut Bob Behnken. A look at lightning strikes, as seen from space. … Taken from 400 km above Earth, the clip shows violet flashes of lightning illuminate the clouds at intervals in a sight that many on the microblogging platform have described as “amazing”.
What planet has the most lightning?
JupiterJuno data indicates that most of the lightning activity on Jupiter is near its poles. Lightning storms on Jupiter are much more frequent, and much less alien, than previously thought, a pair of new studies suggests. The first evidence of lightning on Jupiter was detected nearly 40 years ago.
Does the sun have lightning?
What a great question! Since the sun is made entirely of plasma, which is electrically conductive, my best guess is that there is no lightning there. For lightning to happen we need charge separation by non-conductive medium such as ordinary air.
Is it possible for an electric field to exist at some point in space at which there is no charge?
Q20 Is it possible for an electric field to exist at some point in space at which there is no charge? Yes, all we need to have is a charge somewhere in space that can exert a force on a positive test charge brought to that point in space.
Does lightning create a vacuum?
Thunder is caused by lightning, which is essentially a stream of electrons flowing between or within clouds, or between a cloud and the ground. … As the superheated air cools it produces a resonating tube of partial vacuum surrounding the lightning’s path. The nearby air rapidly expands and contracts.
Can an electric field exist in empty space?
So Electric Fields are vectors (they have magnitude and direction) Electric Fields surround electric charges. Electric Fields exist in empty space (think of fields as a property of space!) … It is present at any (and every) point in space.
How fast does electricity travel in a vacuum?
Light travels through empty space at 186,000 miles per second. The electricity which flows through the wires in your homes and appliances travels much slower: only about 1/100 th the speed of light.
Can you get thunder without lightning?
No, it is not possible to have thunder without lightning. Thunder starts as a shockwave from the explosively expanding lightning channel when a large current causes rapid heating. However, it is possible that you might see lightning and not hear the thunder because it was too far away.
Is Thunder a sonic boom?
A sonic boom is created when an object travels faster than the speed of sound. … The thunder that a storm makes is also a sonic boom caused by lightning forcing air to move faster than the speed of sound.
Where is Lightning Alley?
The area between Tampa Bay on the peninsula’s west coast and Cape Canaveral on the east coast is known as Lightning Alley, and Florida is the lightning capital of the United States — an excellent home for anyone who has an extreme love of thunder and lightning.
Why do electric field lines never cross?
If the lines cross each other at a given location, then there must be two distinctly different values of electric field with their own individual direction at that given location. This could never be the case. … Consequently, the lines representing the field cannot cross each other at any given location in space.
What causes an electric field?
Electric fields are caused by electric charges, described by Gauss’s law, and time varying magnetic fields, described by Faraday’s law of induction. Together, these laws are enough to define the behavior of the electric field.
