SUMMARY
X-ray ionisation plays a crucial role in Millikan's oil drop experiment by charging the oil droplets, enabling the measurement of their charge. The X-ray tube is essential for this process, as it ionises the oil, allowing for the creation of charge on the droplets. However, excessive ionisation can lead to errors in calculations due to the upward attraction of the charged oil drops. Researchers can mitigate this by turning off the X-ray tube before final measurements to prevent overcharging.
