van de graaff generator class 12

van de graaff generator class 12

Van de graf generator

It is a device used to build up very high voltage

Principle

If a hollow conductor is in contact with another conductor,the charge given to conductor is immediately transferred to the hollow conductor to accept large charge due to this potential build up.

Construction and working

It consist of hollow metallic sphere mounted on insulted stand .A belt is run on two pulley .A metal comb C1spray charge and hands .it over to sphere this process continues till up the charge very hight pot.Difference is build up

Uses

It is used to produce accelrated beam of high energy ions to
a) start the nuclear reaction
b) Treat disease like cancer.
c) Breaking of atoms for various experiment.
