Thank you! I was off in the weeds for a few moments...vanhees71 said:
So why do they use Van de Graaff to get charged in the laboratory when this method is simpler and less expensive.Meir Achuz said:

Even a small Van de Graaff generator produces 50,000 volts or more. What kind of practical battery bank are you proposing to achieve that voltage?abdossamad2003 said:
Yes, you can use induction to charge a metal sphere. Induction involves bringing a charged object near the metal sphere without touching it. The presence of the charged object causes a redistribution of charges within the sphere, creating a separation of charge. By grounding the sphere momentarily, you can remove some of the charges, leaving the sphere with a net charge after the charged object is removed.
Yes, conduction is a common method to charge a metal sphere. This involves directly touching the sphere with another object that has a net charge. The charges from the charged object will transfer to the metal sphere, resulting in the sphere acquiring a similar charge.
No, charging a metal sphere using friction is not feasible. Friction typically works for insulating materials where electrons are transferred by rubbing two different materials together. Metals, being conductors, do not hold charge well through friction as the electrons would quickly redistribute.
Yes, a Van de Graaff generator can be used to charge a metal sphere. The generator works by transferring charge to a metal dome, which can then be transferred to the metal sphere either by direct contact or through a conductive path.
Charging a metal sphere using high voltage methods can be dangerous and should be done with caution. High voltage can lead to electric shocks, arcing, and other hazards. Proper insulation, safety protocols, and equipment should be used to mitigate risks when working with high voltage.
