Classic apparatus to measure the fundamental unit of electric charge (e).
- Transparent chamber for clear observation
- Adjustable electric field strength
- Microscope for precise droplet tracking
- Source of ionized air for charging oil droplets
Make precise measurements of the elementary charge (e) using Millikan's classic apparatus. This compact, portable instrument Is made of three main parts: an oil drop chamber, a microscope, and a power supply. Students can observe the charged droplets as they travel across the microscope's field of view. By adjusting the voltage across the interior plates, the charge/mass ratio may be easily calculated. Discover quantized charge for yourself.
