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.

Coulomb per second (C/s) is the SI unit of electric current, representing the flow of electric charge. One coulomb per second is equivalent to one ampere (A). This unit is crucial in understanding how electrical systems operate, as it quantifies the amount of charge passing through a conductor over a specified period.
The coulomb is defined based on the charge carried by a constant current of one ampere flowing for one second. This standardization ensures consistency in electrical measurements across various applications, from household wiring to complex industrial systems.
The concept of electric current has evolved significantly since the 19th century. André-Marie Ampère, a French physicist, was instrumental in defining the relationship between current and charge, leading to the establishment of the ampere as a fundamental unit. The coulomb was later introduced to provide a clear measure of charge, thus enhancing our understanding of electric currents.
To illustrate the use of coulomb per second, consider a circuit where a current of 2 A flows for 5 seconds. The total charge (Q) can be calculated using the formula: [ Q = I \times t ] Where:
So, ( Q = 2 , \text{A} \times 5 , \text{s} = 10 , \text{C} ).
Coulomb per second is widely used in electrical engineering, physics, and various industries where electric current is a critical parameter. Understanding this unit helps professionals design and analyze electrical systems effectively.
To use the Coulomb per Second tool effectively, follow these steps:
What is the relationship between coulombs and amperes?
How do I convert amperes to coulombs per second?
What applications commonly use coulombs per second?
Can I use this tool for both small and large current values?
Is there a difference between coulombs and coulombs per second?
By utilizing the Coulomb per Second tool, you can enhance your understanding of electric current, facilitating better decision-making in your electrical projects and studies. For more information and to access the tool, visit Electric Current Converter.
