Millikan Apparatus 115V

1018882 Includes Only:1 Basic apparatus with experiment chamber and display unit1 Measuring microscope1 Oil atomiser50 ml of oil for Millikan's apparatus1 Plug-in power supply, 12 VAC, 1 AMillikan's Apparatus (115 V, 50/60 Hz). 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.Features:Millikan's experimentDiscrete nature (quantisation) of electric chargeElementary electric chargeCharged oil droplets in an electric fieldStokes viscous drag, weight, buoyancyEquilibrium voltageVelocity of fall and velocity of riseAdvantages:Compact instrument with built-in measurement and display unitTouch-sensitive screen for simple and ergonomic operationMaintenance-free lighting unit for uniform lighting via two green LedsBuilt-in pressure and temperature sensor for automatically determining the relevant parameters, temperature, viscosity and pressure.
