Power Supply for Millikan’s Oil Drop Apparatus

Glass Agencies presents the Power Supply for Millikan’s Oil Drop Apparatus, a specialized educational tool designed to provide accurate and stable voltage necessary for precise experiments on the measurement of the elementary electric charge. This power supply enables students to apply a controlled electric field across the plates of the oil drop apparatus, allowing fine manipulation of tiny charged oil droplets and observation of their motion under the influence of both gravitational and electrical forces. By adjusting the applied voltage, learners can balance the downward gravitational force with the upward electric force, facilitating calculations of droplet charge and enabling verification of Millikan’s experimental results. The unit includes a calibrated voltage control knob, digital or analog display for real-time monitoring, and safe output terminals for connection to the oil drop apparatus, ensuring precise and reliable operation during laboratory experiments. Students can systematically vary voltage and observe the corresponding motion of droplets, reinforcing theoretical principles of electrostatics, forces on charged particles, and fundamental charge quantization. The design prioritizes user safety with built-in protection features to prevent overvoltage, current spikes, or accidental discharge, while maintaining stable output to ensure experimental accuracy. Its compact and sturdy construction supports repeated classroom demonstrations, individual study, and technical training programs, providing long-term reliability and durability. Glass Agencies performs careful quality inspection on each unit to guarantee consistent performance, enabling learners to focus on experimentation and data analysis without equipment-related interruptions. By integrating hands-on voltage control with Millikan’s classical experiment, this power supply bridges the gap between theoretical electrostatics and practical measurement, enhancing comprehension of charge quantization, field effects, and precision experimental techniques. The Power Supply for Millikan’s Oil Drop Apparatus strengthens analytical thinking, observational skills, and measurement accuracy, providing a vital component for physics laboratories, educational institutions, and technical training centers. Its reliability, precise control, and instructional value make it an essential resource for learners seeking to understand the fundamental principles of electric charge through direct experimentation.
