Millikan's Apparatus with Power Supply
Product Code : JA-APE-9407
The Millikan's Apparatus with Power Supply (SKU JA-APE-9407) is a mains-powered version of the Millikan experiment for calculating the charge on a single electron: when it is connected to the mains, the illuminating light and the high-voltage DC to the cell plates are both supplied. In this Millikan's apparatus with built-in power supply, latex solution is atomised into small spheres charged by the rubber hose, and their movement between the charged plates is viewed through a small telescope with a graticule.
Specifications
When powered from the mains the unit lights the cell and applies high-voltage DC to the plates, adjustable by a knob from zero to about 300 V DC, with a polarity reversing switch and sockets for a meter to monitor the cell voltage.

Experiments with the mains-powered Millikan's apparatus
With the supplies built in, a class can move straight to timing the charged spheres between the plates, reversing the field and calculating the charge on each sphere to show that charge is quantised.
- Determination of the charge on a single electron
- Timing charged spheres with the graticule telescope
- Reversing the cell polarity to move spheres towards either plate
- Demonstrating the quantisation of electric charge

Frequently asked questions
What does the built-in power supply provide?
When the unit is powered from the mains, it supplies the illuminating light and the high-voltage DC to the cell.
What is the cell voltage range?
A knob adjusts it from zero to about 300 V DC during an experiment.
How does it differ from the version without power supply?
The version without power supply needs an external high-voltage DC supply and a 12 V illuminator supply connected to its sockets.
