The Ohm (Ω) is the standard unit of electrical resistance in the International System of Units (SI). It quantifies how strongly a material opposes the flow of electric current. Understanding resistance is crucial for anyone working with electrical circuits, as it directly affects the performance and safety of electrical systems.
The Ohm is defined as the resistance between two points of a conductor when a constant potential difference of one volt applied to those points produces a current of one ampere. This standardization ensures consistency and reliability in electrical measurements across various applications and industries.
The term "Ohm" is named after the German physicist Georg Simon Ohm, who formulated Ohm's Law in the 1820s. His work laid the foundation for electrical engineering and the study of circuits. Over the years, the understanding and application of Ohm's Law have evolved, leading to advancements in technology and electrical systems.
To illustrate the use of Ohms, consider a simple circuit with a voltage of 10 volts and a current of 2 amperes. Using Ohm's Law (V = I × R), we can calculate the resistance:
Ohms are widely used in various fields, including electronics, telecommunications, and electrical engineering. They help in designing circuits, troubleshooting electrical issues, and ensuring safety standards are met.

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.
