The smallest unit of electric charge is called an elementary charge. It is the charge carried by a single proton or electron, and its value is approximately 1.602 x 10^-19 coulombs.
The existence of the smallest unit of electric charge was first theorized by physicist Robert Millikan in 1909. He conducted an experiment known as the oil drop experiment, which involved measuring the charge of tiny oil droplets suspended in an electric field. Through this experiment, he was able to determine the value of the elementary charge.
No, the smallest unit of electric charge, or elementary charge, is considered to be indivisible. It is the fundamental unit of charge and cannot be divided into smaller units.
The elementary charge is the fundamental unit of charge in the SI (International System of Units) system. It is used to define other units of charge, such as the coulomb, which is equal to the charge of approximately 6.241 x 10^18 elementary charges.
Yes, the smallest unit of electric charge is the same for all particles. This is because the elementary charge is a fundamental physical constant, meaning it has the same value for all particles that carry it, such as protons and electrons.
