Charging by conduction involves the contact of a charged object to a neutral object. Suppose that a positively charged aluminum plate is touched to a neutral metal sphere. The neutral metal sphere becomes charged as the result of being contacted by the charged aluminum plate.
Hope this helped!
R=U/I so
U=RxI
U= 10 x 42
U= 420 volts
