Higher Physics Lab Atomic & Nuclear Physics



Exp-1 To observe brownian movement in charged oil droplets.
Exp-2 To determine the quantum nature of charge.

  • Quick and accurate measurement.
  • Clarity of drops for measurements.
  • Stability of drops during measurements.
  • Inbuilt power supply.
  • USB Camera.
  • Electron charge.
  • Terminal velocity.
  • Electric field.
  • Brownian motion.
  • Stoke's law.

Millikan oil drop experiment can test and verify the quantum nature of charges, measure the elemental charges and observe the brownian movement.
In the setup SK052 the oil drops are viewed through the eyepiece while in SK052A the motion of oil drops is viewed by USB camera on PC which makes it easier to observe the experiment.
