Abstract
This study investigates the behavior of water droplets acquiring an electrical charge in mineral oil, a non-polar environment. The experimental setup was developed and refined to improve control and understanding of droplet behavior and charge acquisition. Modifications included using a longer acrylic cube and longer electrodes, alongside a DC high-power supply. Droplet detachment was optimized, allowing for better observation of droplet interactions with the mineral oil. Analysis of experimental results revealed that droplet size influences movement dynamics and charge acquisition. The polarity of droplets changed throughout the experiment, which could indicate a time-dependent change in surface charges on the droplet. These findings contribute to understanding droplet behavior in non-polar oil environments.
