Product Overview
The e/m by Millikan’s Oil Drop Method with Power Supply is a complete experimental setup designed for precise measurement of the electron’s charge-to-mass ratio. This apparatus replicates Millikan’s classic oil drop experiment, allowing users to observe and calculate fundamental physical constants with high accuracy. The kit includes a high-quality oil atomizer, parallel plate capacitor assembly, precision voltage control via the integrated power supply, and an optical viewing system for clear droplet observation. The components are constructed from durable, non-reactive materials to ensure long-term reliability and consistent performance. The power supply provides stable, adjustable voltage, enabling fine control over the electric field strength for accurate droplet suspension and measurement. The setup is optimized for educational and laboratory use, offering a hands-on approach to understanding quantum physics principles. The design prioritizes ease of use while maintaining scientific rigor, making it suitable for both introductory and advanced experiments.
FAQs
1. What is the voltage range required for this Millikan’s oil drop setup?
The integrated power supply is designed to provide the necessary voltage range for suspending oil droplets, typically between 0-500V, which is adjustable for precise experimentation.
2. Can this apparatus be used for demonstrations in classrooms?
Yes, the complete setup is designed for educational purposes, including classroom demonstrations, with clear visualization and straightforward operation.
3. What type of oil is recommended for this experiment?
The experiment traditionally uses lightweight, low-volatility oils like mineral oil or silicone oil, which are stable and produce consistent droplet behavior.
4. How should the apparatus be stored when not in use?
Store the components in a dry, dust-free environment, preferably in the original packaging or a protective case to prevent damage to the optical and electrical parts.
5. Is calibration required before conducting the experiment?
While the setup is pre-configured for standard experiments, recalibration of the voltage and optical alignment may be necessary for optimal accuracy, especially after transportation or prolonged storage.
