The milliampere-hour (mAh) is a unit of electric charge commonly used to measure the capacity of batteries. It represents the amount of electric charge transferred by a current of one milliampere flowing for one hour. This measurement is crucial for understanding how long a battery can power a device before needing to be recharged.
The milliampere-hour is part of the International System of Units (SI) and is derived from the base unit of electric current, the ampere (A). One milliampere is equal to one-thousandth of an ampere, making the mAh a practical unit for measuring smaller battery capacities, especially in consumer electronics.
The concept of measuring electric charge dates back to the early 19th century with the development of the first batteries. As technology advanced, the need for standardized measurements became apparent, leading to the adoption of the milliampere-hour as a common metric in the battery industry. Over time, the mAh has become a vital specification for consumers looking to understand battery life in devices such as smartphones, laptops, and electric vehicles.
To illustrate how milliampere-hours work, consider a battery rated at 2000 mAh. If a device draws a current of 200 mA, the battery can theoretically power the device for: [ \text{Time (hours)} = \frac{\text{Battery Capacity (mAh)}}{\text{Current (mA)}} = \frac{2000 \text{ mAh}}{200 \text{ mA}} = 10 \text{ hours} ]
The milliampere-hour is widely used in various applications, including:

1. What is the difference between milliampere and milliampere-hour? The milliampere (mA) measures electric current, while milliampere-hour (mAh) measures the total electric charge over time.
2. How do I calculate the battery life using mAh? To calculate battery life, divide the battery capacity in mAh by the device's current draw in mA.
3. Is a higher mAh rating always better? Not necessarily. While a higher mAh rating indicates a longer battery life, it is essential to consider the device's power requirements and efficiency.
4. Can I convert mAh to other units of charge? Yes, you can convert mAh to other units such as ampere-hours (Ah) by dividing by 1000, as 1 Ah = 1000 mAh.
5. How does temperature affect battery capacity measured in mAh? Extreme temperatures can affect battery performance and capacity. It is advisable to use batteries within the manufacturer's recommended temperature range for optimal performance.

The kilocoulomb per hour (kC/h) is a unit of electric charge flow, representing the amount of electric charge (in kilocoulombs) that passes through a conductor in one hour. This unit is particularly useful in electrical engineering and physics, where understanding the flow of electric charge is crucial for designing and analyzing circuits.
The kilocoulomb is derived from the coulomb, which is the standard unit of electric charge in the International System of Units (SI). One kilocoulomb equals 1,000 coulombs. The standardization of this unit allows for consistent measurements across various scientific and engineering applications.
The concept of electric charge dates back to the early studies of electricity in the 18th century. The coulomb was named after Charles-Augustin de Coulomb, a French physicist who made significant contributions to electrostatics. Over time, as electrical engineering evolved, the need for larger units like the kilocoulomb became apparent, especially in high-voltage applications.
To illustrate the use of kilocoulomb per hour, consider a scenario where an electric circuit allows a charge of 5 kC to flow in one hour. This can be expressed as:
