Question

Van de Graaff generator is used for

• A. Production of X-ray beam.
• B. Generating large currents.
• C. Storing electrical energy
• D. Generating high potential of the range of few million volts.

Answer 1

The correct option is D Generating high potential of the range of few million volts.

Van de Graaff generator is an electrostatic-accelerator that is used for scientific experiments to get high voltages in less time with a high safety factor.

It generates very high potential, so the charged particles can be accelerated to a very high kinetic energy as $KE=q\Delta V$.

These high energy beams are used to study collision experiments in physics.

Hence, option (d) is the correct answers.
