how many volts is thunder from the sky
Answers
Answer:
There may be many millions of volts between the end points where a lightning strike is going to occur. These high voltages lead to the generation of ion paths or channels forming, which are close to a short circuit as far as the actual discharge is concerned. Once the ion channel is established there may be only a few thousand volts across the length of the channel, but a very high current typically somewhere around 30 kA for an average strike but possibly approaching 0.5 MA (half a million amps) for the largest lightning bolts.
A single lightning occurrence may actually be made up of multiple strikes in quick succession, giving the appearance of a single lightning bolt that might snake around a bit as the different strikes occur.
A similar effect occurs in a full size (say 5 foot to 8 foot) fluorescent tube. A high voltage of several thousand volts may be applied across the tube to cause an ion channel to form. This voltage is generated by a choke (inductor) in series with the tube. The lamps starter shorts out the tube so that the so that current can flow, and at the same time, this current drives heaters at each end of the tube to produce electrons to help start the ionisation process. When the starter fires, it suddenly open circuits, and the current in the inductor produces the high voltage pulse to start ionisation. Once the channel is established, the tube will only have a few tens of volts across it in a similar manner to a lightning bolt. In the case of the lamp, the choke limits the current to a safe level.
As with lightning it is sometimes possible to see a swirling effect in the illumination of the tube as the ion channel moves around between successive current pulses caused by the AC supply.
