    Capacitor Earth
AI Thread Summary
The discussion centers on the process of lightning formation, emphasizing that differing charges between clouds and the ground lead to electrical discharges during rain. Clouds acquire charge through friction, similar to static electricity, which can result in cloud-to-cloud or cloud-to-ground lightning. Participants encourage further exploration of the topic, suggesting that self-study can enhance understanding. Engaging with specific questions can help focus discussions and provide more targeted assistance. Overall, curiosity about the science of lightning is welcomed and encouraged.

dear sir
the charge on clouds and ground can be different and this causes lightning due rain only. i want to know more about the process that causes it
 
Astronomy news on Phys.org
Clouds become charged by rubbing against one another, not unlike rubbing a glass rod with a silk cloth. When the charge becomes sufficiently disparate you can have cloud to cloud, or cloud to ground electrical discharges [i.e., lightning].

Go ahead and read All About Lightning, by Martin Uman. Only $6.95 from Dover.
 
shivakumar, you "want to know" all about all kinds of neat subjects. So do we all.

That's a healthy curiosity, and good to see, however the subjects tend to get quite big so it is difficult to know how best to help you.

The way to get best value from these forums is to read about the subjects oneself and then ask questions about it where you get stuck. The questions are a way we can narrow down our replies to things that will be helpful.
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
