The milliampere-hour (mAh) is a unit of electric charge that is commonly used to measure the capacity of batteries. It indicates how much current a battery can deliver over a specific period. For instance, a battery rated at 1000 mAh can theoretically provide 1000 milliamperes (mA) of current for one hour before it is fully discharged.
The milliampere-hour is part of the International System of Units (SI) and is derived from the ampere, which is the base unit of electric current. The symbol for milliampere-hour is mAh, where "milli" denotes a factor of one-thousandth. This standardization allows for consistent measurements across various applications, making it easier for users to understand battery capacities and performance.
The concept of measuring electric charge dates back to the early days of electricity. The milliampere-hour emerged as a practical unit in the 20th century, particularly with the rise of portable electronic devices. As technology advanced, the demand for efficient battery capacities increased, leading to the widespread adoption of mAh as a standard measurement in consumer electronics.
To illustrate how to use the milliampere-hour measurement, consider a smartphone battery rated at 3000 mAh. If the phone consumes 300 mA of current during usage, you can calculate the approximate usage time as follows:
[ \text{Usage Time (hours)} = \frac{\text{Battery Capacity (mAh)}}{\text{Current Consumption (mA)}} ] [ \text{Usage Time} = \frac{3000 \text{ mAh}}{300 \text{ mA}} = 10 \text{ hours} ]
The milliampere-hour is crucial for consumers when selecting batteries for devices such as smartphones, tablets, and laptops. Understanding mAh helps users gauge how long their devices can operate on a single charge, enabling informed decisions when purchasing or replacing batteries.

The Electrostatic Unit (ESU), often denoted as "esu," is a unit of electric charge in the electrostatic system of units. It is primarily used in theoretical physics and electrostatics to quantify the amount of electric charge that produces a force of one dyne between two point charges separated by one centimeter in a vacuum.
The ESU is part of the Gaussian system of units, which is a set of units used in electromagnetic theory. Unlike the International System of Units (SI), which uses coulombs for electric charge, the ESU provides a different perspective on electric phenomena, making it essential for specific scientific applications.
The concept of the electrostatic unit dates back to the early studies of electricity in the 19th century. Pioneers like Charles-Augustin de Coulomb laid the groundwork for understanding electric forces, leading to the establishment of the ESU. Over time, as scientific understanding evolved, the ESU became less common in practical applications but remains crucial in theoretical physics and electrostatics.
To illustrate the use of the electrostatic unit, consider two point charges, each with a charge of 1 esu, placed 1 cm apart. According to Coulomb's law, the force (F) between the charges can be calculated as: [ F = \frac{k \cdot |q_1 \cdot q_2|}{r^2} ] Where:
The electrostatic unit is particularly useful in theoretical calculations involving electric fields, forces, and potentials. It serves as a bridge between classical mechanics and electromagnetic theory, allowing scientists to explore the interactions between charged particles.
