The ampere-hour (Ah) is a unit of electric charge that represents the amount of electric charge transferred by a steady current of one ampere flowing for one hour. It is commonly used to measure the capacity of batteries, indicating how long a battery can deliver a specific current before it is depleted.
The ampere-hour is standardized under the International System of Units (SI) and is derived from the ampere, which is the base unit of electric current. The relationship between ampere-hours and coulombs (the SI unit of electric charge) is defined as: 1 Ah = 3600 coulombs.
The concept of measuring electric charge dates back to the early days of electricity. The ampere-hour was introduced as a practical way to quantify battery capacity, allowing users to understand how long a battery can power a device. Over the years, advancements in battery technology have made the ampere-hour a crucial metric in various applications, from consumer electronics to electric vehicles.
To illustrate how to calculate ampere-hours, consider a battery that supplies a current of 2 amperes for 5 hours. The total charge in ampere-hours can be calculated as follows: [ \text{Total Charge (Ah)} = \text{Current (A)} \times \text{Time (h)} ] [ \text{Total Charge (Ah)} = 2 , \text{A} \times 5 , \text{h} = 10 , \text{Ah} ]
The ampere-hour is widely used in various fields, including:

The microampere (µA) is a unit of electric current that is equal to one-millionth of an ampere (A). It is commonly used in electronics and electrical engineering to measure small currents, particularly in sensitive devices such as sensors and microcontrollers. Understanding microamperes is essential for professionals and hobbyists working with low-power circuits.
The microampere is part of the International System of Units (SI) and is derived from the base unit of electric current, the ampere. The symbol for microampere is µA, where "µ" denotes the metric prefix "micro," representing a factor of 10^-6. This standardization ensures consistency and accuracy in measurements across various applications and industries.
The concept of measuring electric current dates back to the early 19th century, with André-Marie Ampère being one of the pioneers in the field of electromagnetism. The microampere emerged as technology advanced, particularly with the development of low-power electronics in the late 20th century. As devices became more compact and energy-efficient, the need for measuring smaller currents became increasingly important, leading to the widespread use of the microampere in modern applications.
To convert a current measurement from milliamperes (mA) to microamperes (µA), you can use the following formula:
[ \text{Current (µA)} = \text{Current (mA)} \times 1000 ]
For instance, if you have a current of 5 mA, the equivalent in microamperes would be:
[ 5 , \text{mA} \times 1000 = 5000 , \text{µA} ]
Microamperes are particularly useful in applications such as:
