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 volt per ohm (V/Ω) is a derived unit of electric current, representing the flow of electric charge in relation to the resistance in an electrical circuit. This unit is crucial for understanding Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R). Therefore, V/Ω is equivalent to amperes (A), making it a vital unit in electrical engineering and physics.
The volt per ohm is standardized within the International System of Units (SI), where:
The concept of electric current has evolved significantly since the 19th century, with pioneers like Georg Simon Ohm and André-Marie Ampère laying the groundwork for our understanding of electricity. The volt, named after Alessandro Volta, and the ohm, named after Georg Simon Ohm, have become fundamental units in electrical science. The relationship between these units has been pivotal in developing modern electrical systems and technologies.
To illustrate the use of the volt per ohm, consider a circuit with a voltage of 12 volts and a resistance of 4 ohms. Using Ohm's Law: [ I = \frac{V}{R} = \frac{12V}{4Ω} = 3A ] Thus, the current flowing through the circuit is 3 amperes, which can also be expressed as 3 V/Ω.
The volt per ohm is primarily used in electrical engineering, physics, and various applications involving electrical circuits. It helps engineers and technicians calculate current flow, design circuits, and troubleshoot electrical issues.
To interact with the volt per ohm tool on our website, follow these simple steps:
What is volt per ohm (V/Ω)? Volt per ohm is a unit of electric current, defined as the flow of electric charge resulting from a voltage divided by resistance.
How do I convert volts and ohms to amperes? You can convert volts and ohms to amperes using Ohm's Law: I (A) = V (V) / R (Ω).
Why is understanding V/Ω important? Understanding volt per ohm is essential for designing and troubleshooting electrical circuits, ensuring safety and efficiency.
