Is lightning visible electricity?
Lightning is a visible electrical discharge from a cloud. This happens when there is an imbalance of charges between a region of the cloud and another surface (usually the ground, a building, another region of the same cloud, or another cloud) that is significant enough to break through air resistance.
Why is lightning not used for electricity?
The problem is that the energy in lightning is contained in a very short period of time, only a few microseconds. Further, to obtain that 1 million joules, one would have to handle a voltage of several million volts.
Is electricity visible or invisible?
It’s like gravity – an invisible force we only recognise when it acts upon other objects. In the instance of electricity, the most common way it affects objects is by charging electrons, and because these are so small, so plentiful and move so quickly once charged, they are all but invisible to the naked human eye.
Why can we see lightning?
Lightning is visible as a flash of light because of both incandescence (due to its high temperature it glows blue-white) and luminescence (excitation of nitrogen gas in the atmosphere). Nitrogen, the dominant gas in the atmosphere, is excited by this strong flow of energy, its electrons moving to higher energy states.
Why do I get shocked when I touch everything?
Static shocks are more common when it’s cold and dry. This dry, cold air holds less water vapour than warm summer air. So, when you touch something like a metal doorknob or car door, those extra electrons will rapidly leave your body and give you the shock.
You can see lightning because it si NOT just “electricity power”. What you see when you see lightning is the light given off by air molecules ionized by the electric current. You are not seeing the electricity itself. You have never seen an electrical spark?
Where does the energy of lightning go?
The energy goes through the air. It goes to a place that has the opposite charge. This lightning bolt of energy that is let out is called a leader stroke. It can go from the cloud to the ground. Or, a leader stroke can go from the cloud to another cloud.
What is the difference between lightning and electric current?
The only difference is there frequency. The frequency of lightning is in the spectrum of visible light. The frequency of electric current is out of the spectrum of visible light, therefore we can see lightning and not electric current. , I not only understood the science I studied at Reed, I kept up the reading.
Why can’t we see electricity?
Simple enough. We don’t see the electricity, we see the light energy generated by the lightning. If we keep this in mind then we always keep seeing electricity, the light on your screen, whatever device it is was generated by electricity. We cannot see electricity in its simplest form, it is just power.
