MILLIKAN'S APPARATUS WITH POWER SUPPLY

  • AP2131-001

Millikan's apparatus with inbuilt power supplies permits the atomising of a latex solution into small spheres and the rubber hose induces a static charge upon them. They are introduced between charged plates in the form of a cell. As the voltage between these cell plates is reversed, the particles are attracted to one plate or the other. Their movement is viewed through a small telescope with a graticule. The required power sources are inbuilt. Knowing the potential on the cell plates and plotting the velocities of the spheres permits the calculation of the charge on a single electron.
