Thematic focus:_..

•	Produce and select suitable oil drops and observe them in an electric field.
•	Measure the speed with which they rise in the electric field and descend without it.
•	Confirm the value of the elementary charge.

Product Information:_..

Compact apparatus for demonstrating the discrete nature (quantisation) of electric charge and for determining the elementary charge of an electron. Comprising an experiment chamber kit for assembly with plate capacitor and connected oil atomiser, lighting unit with two green LEDs, measuring microscope, voltage adjustment knob and switch to set the capacitor voltage, switch for starting and stopping rise and fall time measurements and a display unit with touch screen. Measurements can be made using the floating method or the rising and falling method. Measured rise and fall times for a charged droplet of oil are displayed on the touch screen along with the configured voltage. Parameters relevant to the evaluation of the results, temperature, viscosity and pressure are also displayed.
Includes plug-in power supply, 12 VAC, 1 A.
