Question

Lightning is a great illustration from nature of the stunning application of statics and electric fields. There are over 15 different types of lightning. Do a bit of research and select a lightning type that you find interesting. Try to use a different example than those given by your classmates. Address the following discussion item

• What do you find interesting about the type of lighting you selected?
• Describe your lightning type.
• Include a photo, video, or illustration.
• Give a scientific explanation of how your lighting type occurs. Include how charging (or charge separation) occurs..
• What role does induction play?
• Do you think it's feasible to harness the power of lightning? Why or why not. Provide facts to support your position.
• Besides statics and electric fields, give one more example of a physics principle illustrated by lightning.

Answer 1

1. What do you find interesting about the type of lighting you selected?

In the lightning process naturally, a huge amount of light and sound is created by the atmosphere, so it is more interesting how it generating, so I selected to find the solution on this.

1. Describe your lightning type.

There more number of lighting process are available those are

1. Cloud-to-Ground Lightning - Negative charge movement
2. Cloud-to-Ground Lightning – Positive charge movement
3. Ground-to-Cloud Lightning- negative/ positive charge movement
4. Intracloud Lightning: charges will move between the cloud to cloud, etc. in those type most common lighting is cloud-to-ground lighting.

Q: Give a scientific explanation of how your lighting type occurs. Include how charging (or charge separation) occurs..

Answer :

Lightning is naturally happening electrostatic discharge. The movement of charges at clouds rapid to ground will generates lighting as well as sound. Generally when the rain droplets are coming from the clouds they will creates frictional forces with the atmospheric molecules, hence charge separation will happen between atmospheric molecules and rain water molecules which are coming to ground due to this positive/negative charges will accumulate in the atmosphere when this process is continuing more number of positive/negative charges will accumulate in the sky. As we know that earth is a pool of negative/positive charges. According to the electrostatic force between the two opposite charges will attract to each other this attraction forces directly depends on quantity of the charges so if more charges are separated this value will become more. When sufficient of attraction force is creates this charges can move suddenly, at this movement they creates light as well as sound so it is named as lightning. The average energy of one lighting is one billon joule (1,000,000,000 joules energy )

Question : Do you think it's feasible to harness the power of lightning? Why or why not. Provide facts to support your position.

Answer :

A worldwide research is going on to harness the power of lightning for utilize this energy for human life. But due to lack of knowledge on how to store this huge amount charge in faction of second and there is no such a huge battery was made to store this one billon (1,000,000,000) joules energy ( average energy of one lighting ) very small interval time. Hence we are unable to harness the lightning power in present generation we hope the upcoming generation by be store this and can utilize this.
