The kilowatt-hour (kWh) is a standard unit of energy commonly used to measure electricity consumption. It represents the amount of energy consumed when a device with a power rating of one kilowatt operates for one hour. Understanding kWh is essential for managing energy usage effectively, whether for residential, commercial, or industrial applications.
The kilowatt-hour is standardized under the International System of Units (SI) and is widely accepted across various industries. It is essential for energy billing, allowing consumers to understand their electricity usage and costs clearly.
The concept of the kilowatt-hour emerged in the late 19th century as electricity became a common utility. With the advent of electric power generation and distribution, the need for a standardized measure of energy consumption became crucial. Over the years, the kWh has evolved to become a fundamental unit in energy management and sustainability discussions.
To illustrate how to calculate kWh, consider a 100-watt light bulb used for 10 hours. The calculation would be:
[ \text{kWh} = \frac{\text{Power (in watts)}}{1000} \times \text{Time (in hours)} ]
[ \text{kWh} = \frac{100 \text{ watts}}{1000} \times 10 \text{ hours} = 1 \text{ kWh} ]
The kilowatt-hour is primarily used in electricity billing, energy consumption analysis, and efficiency assessments. It helps consumers understand their energy usage patterns and make informed decisions about energy conservation.

The electronvolt (eV) is a unit of energy commonly used in the fields of physics and chemistry. It is defined as the amount of kinetic energy gained or lost by a single electron when it is accelerated through an electric potential difference of one volt. This unit is particularly useful for measuring small amounts of energy, such as those encountered in atomic and subatomic processes.
The electronvolt is part of the International System of Units (SI) but is not an SI unit itself. Instead, it is derived from the SI unit of energy, the joule (J). Specifically, 1 eV is equivalent to approximately (1.602 \times 10^{-19}) joules. This relationship allows for easy conversion between electronvolts and joules, making it a versatile unit in scientific calculations.
The concept of the electronvolt emerged in the early 20th century as physicists began to explore the behavior of electrons and other subatomic particles. The term was first used in 1900, and since then, it has become a standard unit in various scientific disciplines, including particle physics, quantum mechanics, and solid-state physics. Its widespread adoption reflects the growing importance of understanding energy at the atomic level.
To illustrate the use of the electronvolt, consider a scenario where an electron is accelerated through a potential difference of 5 volts. The energy gained by the electron can be calculated as follows:
[ \text{Energy (eV)} = \text{Charge (C)} \times \text{Voltage (V)} = (1.602 \times 10^{-19} \text{ C}) \times (5 \text{ V}) = 8.01 \times 10^{-19} \text{ J} \approx 5 \text{ eV} ]
The electronvolt is predominantly used in fields such as:
