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 picocoulomb (pC) is a unit of electric charge in the International System of Units (SI). It represents one trillionth (10^-12) of a coulomb, which is the standard unit of electric charge. The picocoulomb is commonly used in various scientific and engineering applications, particularly in fields related to electronics and electrostatics.
The picocoulomb is standardized under the SI system, ensuring consistency and reliability in measurements across different scientific disciplines. This standardization allows for precise calculations and comparisons in research, development, and practical applications involving electric charge.
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 conducted pioneering work in electrostatics. As technology advanced, the need for smaller units became apparent, leading to the adoption of the picocoulomb for measuring minute quantities of charge, especially in semiconductor technology and microelectronics.
To illustrate the use of picocoulombs, consider a scenario where a capacitor stores a charge of 5 pC. If you need to convert this charge into coulombs, the calculation would be:
[ 5 , \text{pC} = 5 \times 10^{-12} , \text{C} ]
This conversion is essential for understanding the behavior of electrical components in circuits.
Picocoulombs are particularly useful in fields such as:
