Introduction

This LEAI**2 apparatus of Millikan's oil drop experiment is the advanced version of the series with CCD image acquisition and monitor display, it is designed to verify the quantum nature of electrical charges, measure the elementary charge of an electron, experiment on the Brownian motion, and verify normal distribution of displacement probability. It is an ideal teaching apparatus for physics laboratories in colleges and universities.

This apparatus possesses the following advantages:

1. Electronic graduation scales are stable, not affected by the distortion of the display.

2. Image of oil drops is clear and bright with a high contrast.

3. Better observation of Brown movement with a **0X TV microscope.

4. Graduation scale, voltage, time, and oil drop image displayed on one screen.

5. Output signal compatible with various display devices such as TV, projector, recorder and so on.

Using this apparatus, the following experiments can be conducted:

1. Verify the existence of positive and negative electrical charges

2. Verify the quantum nature of electrical charges

3. Measure the elementary charge of an electron

4. Observe and measure Brownian motion (optional)

5. Verify normal distribution of displacement probability (optional)
