The Van de Graaf generator includes a metal sphere of radius R electrically isolated from its surround- ings except for a wire which can carry a current. When the current is a steady 5.0 μA, it takes 1.3 s for the sphere to reach its operating potential of 4.0x102 kV if it’s initially uncharged. What is R? (a) 1.5 m (b) 2.4 m (c) 0.15 m (d) 0.30 m (e) None of the above

Construct Your Own Problem. Consider a battery used to supply energy to a cellular phone. Construct a problem in which you determine the energy that must be supplied by the battery, and then calculate the amount of charge it must be able to move in order to supply this energy. Among the things to be considered are the energy needs and battery voltage. You may need to look ahead to interpret manufacturer’s battery ratings in ampere-hours as energy in joules.
