How does lightning work? (one strike or multiple strikes?)

AI Thread Summary
Thunderclouds can release energy in multiple lightning strikes rather than a single discharge, as they often produce both primary and secondary strikes. Voltage does not flow in lightning; instead, current flows when the electric field between the cloud and ground overcomes air resistance. Discharges can consist of a single strike or multiple pulses along the same path, with currents reaching hundreds of amps. The process involves a buildup of electric potential that repeats after each discharge. Understanding this cycle clarifies how thunderclouds can generate multiple lightning strikes.

I am mainly asking if it's possible for a thunder cloud to release its sorted energy in burst rather than in one strike. Like if a thundercloud had 1 billion volts would it be possible to great small sparks that allow it to shoot of 5 lighting strikes of different voltages rather than one strike of 1 billion volts.

Sometimes when there is sever lightening, you can see multiple strikes released from a thunder cloud consecutively. Is that what you mean? Usually, you will see one large strike with branches. Then secondary strikes that follow the initial bolt of lightning follows shortly. All of this is an attempt to neutralize charge.
 
Oh, and this is rather thrilling:

Something like that. What I am really asking is say you had a thundercloud. It had 1 billion volts stored in it. Now when it discharges, a single or what you said 2 bolts of lighting. What I want to know is,(with the help of man or just by itself) would it be possible for the thunder cloud to release all of its stored energy in burst of electricity. Sort of like a batter expect it gives off energy in burst of multiple strike.

hi there
you have a bit of a misunderstanding of voltage. Voltage DOESNT flow in the lightning strike or in any other situation, Current does.
As the voltage( potential difference between the cloud and the ground, or between 2 points in a cloud, build up, an electric field is
generated between say, the cloud and the ground. This electric field needs to build up to a point where it overcomes the air gap resistance
between the cloud and the ground. Once that potential difference is reached, a discharge occurs, and current flows.

There are some finer details of the initiating of the discharge, you can google lightning leaders and streamers

During the discharge, huge amounts of current flows, often 10's of 100's of Amps
Some strikes are primarily a single discharge down the channel path. Others are multiple discharges down the same path.
I have often counted and or videoed up to 7 or 8 pulses down the same path

Once the discharge has occurred, the voltage ( potential difference = electric field again starts to build up and the cycle repeatsDave
 
Thread 'Simple math model for a Particle Image Velocimetry system'
Hello togehter, I am new to this forum and hope this post followed all the guidelines here (I tried to summarized my issue as clean as possible, two pictures are attached). I would appreciate every help: I am doing research on a Particle Image Velocimetry (PIV) system. For this I want to set a simple math model for the system. I hope you can help me out. Regarding this I have 2 main Questions. 1. I am trying to find a math model which is describing what is happening in a simple Particle...
Thread 'How to model converging illumination through object plane (in ZEMAX)'
Hello community, I'm designing a projection lens system for a 35mm film projector in Zemax OpticStudio and struggling with the correct sequential mode setup for the illumination geometry. The light source is a Xenon short-arc lamp reflected by an ellipsoid mirror, which creates a converging cone with a 40.6 degree full angle that passes through the film gate. The film gate is my object plane, but the light doesn't diverge from it like a typical Lambertian source. Instead, the converging...
