Millikan Oil Drop Apparatus

The Millikan Oil Drop Experiment is designed to determine the elementary electric charge, the fundamental unit of charge carried by an electron. The apparatus demonstrates the quantization of electric charge by balancing gravitational and electrical forces acting on charged oil droplets suspended within an electric field. Its modern design enables precise observation and accurate experimental analysis, making it an ideal educational tool for physics laboratories. Manufactured by Atico Export India.

Principle

The experiment determines the elementary electric charge by balancing the gravitational force with the electrical force acting on charged oil droplets suspended in an electric field. By observing and measuring the motion of these droplets, the elementary charge and the quantized nature of electric charge can be accurately determined.

Objectives

• Determine the elementary electric charge carried by an electron.
• Verify the quantization of electric charge.
• Demonstrate the balance between gravitational and electrical forces acting on charged oil droplets.
