Charging a metal sphere using a battery connected to the ground is effective, as the sphere becomes electrically charged to the extent of Q=VR in Gaussian units. This method is simpler and less expensive than using a Van de Graaff generator, which typically produces over 50,000 volts. However, achieving such high voltages with a battery requires an electric converter to step up the voltage, such as converting 220V to 50kV using a diode. The discussion highlights the practicality of using batteries for charging compared to traditional laboratory methods.
PREREQUISITESElectronics enthusiasts, physics students, and engineers interested in electrostatics and high-voltage applications will benefit from this discussion.
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:
What is the difference in voltage for a Van de Graaff generator versus a battery?abdossamad2003 said:
The battery voltage can be increased enough to match the voltage produced by the van devGraaffberkeman said:What is the difference in voltage for a Van de Graaff generator versus a battery?
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:
