Question
Physics Question on electrostatic potential and capacitance
Van de Graaff generator is used to
A
store electrical energy
B
build up high voltages of few million volts
C
decelerate charged particle like electrons
D
both (a) and (b) are correct
Answer
build up high voltages of few million volts
Explanation
Solution
Van de Graff generator- is an electrostatic generator which is devised to produce very high voltage by means of an endless belt collecting electrostatic charge from a source and transferring it to a large isolated metal sphere on which a large change accumulates.
