The elementary charge, denoted by the symbol e, is the smallest unit of electric charge that is considered indivisible. It is a fundamental physical constant that represents the charge carried by a single proton, which is approximately 1.602 x 10^-19 coulombs. This unit is crucial in the field of physics, particularly in electromagnetism and quantum mechanics, as it forms the basis for the charge of all matter.
The elementary charge is standardized in the International System of Units (SI) and is a cornerstone in the study of electric charge. It is essential for calculations involving atomic and subatomic particles, allowing scientists to quantify interactions in a consistent manner.
The concept of elementary charge has evolved significantly since the early 20th century when physicists began to understand the atomic structure. The discovery of the electron by J.J. Thomson in 1897 and the subsequent work by Robert Millikan in the early 1900s, which included the famous oil-drop experiment, helped to establish the value of the elementary charge. This historical context is vital for understanding how fundamental particles interact and the role of charge in the universe.
To illustrate the application of elementary charge, consider a scenario where you have a charge of 3e. This means you have three times the elementary charge, which can be calculated as follows:
[ \text{Total Charge} = 3 \times e = 3 \times 1.602 \times 10^{-19} \text{ C} \approx 4.806 \times 10^{-19} \text{ C} ]
This calculation is essential in various fields, including chemistry and physics, where understanding the charge of particles is crucial.

The megaampere-hour (MAh) is a unit of electric charge that represents one million ampere-hours. It is commonly used in the field of electrical engineering and battery technology to quantify the total charge capacity of batteries and other electrical storage systems. Understanding this unit is essential for professionals and enthusiasts working with large-scale electrical systems.
The megaampere-hour is standardized within the International System of Units (SI) and is derived from the ampere, which is the base unit of electric current. One MAh is equivalent to 3.6 billion coulombs, as it is calculated by multiplying the current (in amperes) by the time (in hours) that the current flows.
The concept of measuring electric charge dates back to the early discoveries of electricity in the 18th century. As technology advanced, the need for standardized measurements became crucial, leading to the establishment of the ampere as a base unit in the late 19th century. The megaampere-hour emerged as a practical unit for measuring large quantities of electric charge, especially in industrial applications and energy storage systems.
To illustrate how to use the megaampere-hour, consider a scenario where a battery discharges at a current of 2 MAh for 5 hours. The total charge delivered can be calculated as follows: [ \text{Total Charge (MAh)} = \text{Current (MA)} \times \text{Time (h)} ] [ \text{Total Charge} = 2 , \text{MA} \times 5 , \text{h} = 10 , \text{MAh} ]
The megaampere-hour is particularly useful in applications such as:
