Main technical parameters and characteristics:
This experiment proves that the charge of any charged body is an integral multiple of the basic charge, which clarifies the discontinuity of the charge and accurately determines the value of the basic charge.
Distance between parallel plates: 5.00±0.01mm
Measuring microscope magnification: 60
Microscope reticle full scale equivalent: 3.00 ± 0.01mm
CCD display reticle full scale: 2.00 ± 0.01mm
Continuous tracking of charged oil droplets: >2h
CCD electronic display system resolution: ≥ 420TV line
Average relative error ≤ 3%, with 9-inch black and white monitor
Experimental content: 1. Determination of the amount of electron charge
2. Verify the discontinuity of the measured charge
3. Observing Brownian motion
Remarks: The instrument is equipped with an electronic network based on DP/MOD-5B. The voltmeter, electronic stopwatch, single chip microcomputer and electronic grid are displayed on the same screen.
