Chapter 33, Problem 20A
How much voltage can be built up on a Van de Graaff generator of 1 m radius before electric discharge occurs through the air?
Expert Solution & Answer
To determine
To explain: Voltage can be built up on a Van de Graaff generator of 1 m radius.
Explanation of Solution
A sphere with a radius of 1 meter can be raised to a potential of about 3 million volts (in air), because air remain insulator in maximum electric field of about 3 x 106 V/m.
