Excuse me, but could you please clarify your question? It seems a bit unusual to inquire about the number of volts in a cloud. As you may know, volts are a unit of electrical potential or electromotive force, typically used in the context of electricity and electronics. Clouds, on the other hand, are made up of water droplets or ice crystals suspended in the atmosphere, and they don't possess any electrical potential in the same sense as a battery or electrical circuit.
Perhaps you're referring to the phenomenon of lightning, which is caused by electrical charges building up in clouds and then discharging through the air. In that case, the voltage of a lightning bolt can be extremely high, reaching millions of volts in some cases. But it's important to note that this voltage is only present during the brief moment of the lightning strike, and it's not something that can be measured or quantified in a cloud itself.
So, to summarize, the concept of volts doesn't really apply to clouds in the way you're asking. If you have a specific question about electricity, clouds, or lightning, I'd be happy to try and provide a more accurate answer.
