MCQ
What is the order of potential difference built up by the Van de Graff generator?
  • A
    Potential difference of the order of hundreds.
  • ✓
    Potential difference of the order of several million volts.
  • C
    Potential difference of the order of thousands.
  • D
    Potential difference of the order of tens.
✓

Answer

Correct option: B.
Potential difference of the order of several million volts.
A Van de Graff generator, by means of a moving belt and suitable brushes, transfers charge continuously to a large spherical conducting shell. As a result, a potential difference of the order of several million volts is built up and this can be used for accelerating charged particles.
