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 kiloohm (symbol: kΩ) is a unit of electrical resistance in the International System of Units (SI). It represents one thousand ohms (1 kΩ = 1,000 Ω). This unit is commonly used in electrical engineering and physics to measure resistance in circuits, ensuring that electrical components function correctly and safely.
The kiloohm is part of the metric system, which is standardized globally. This unit is widely accepted in scientific and engineering communities, making it essential for professionals and students alike. The kiloohm is particularly useful when dealing with high resistance values, allowing for easier calculations and comparisons.
The concept of electrical resistance dates back to the early 19th century, with Georg Simon Ohm's formulation of Ohm's Law. As technology advanced, the need for standardized units became apparent, leading to the adoption of the kiloohm as a convenient measure for larger resistances. Over the years, the kiloohm has remained a fundamental unit in electrical engineering, adapting to new technologies and applications.
To illustrate how to convert resistance values, consider a resistor rated at 5 kΩ. If you need to express this value in ohms, the calculation is straightforward: [ 5 , kΩ = 5 \times 1,000 , Ω = 5,000 , Ω ] Conversely, if you have a resistance of 2,500 Ω and want to convert it to kiloohms: [ 2,500 , Ω = \frac{2,500}{1,000} , kΩ = 2.5 , kΩ ]
Kiloohms are frequently used in various applications, including:
