The joule per coulomb (J/C) is a derived unit of electric potential, also known as voltage. It quantifies the amount of energy (in joules) per unit charge (in coulombs) and is crucial in understanding electric circuits and systems. Essentially, it indicates how much energy is available to move electric charges through a circuit.
The joule per coulomb is standardized in the International System of Units (SI). In this system, one joule is defined as the energy transferred when a force of one newton is applied over a distance of one meter. One coulomb is defined as the quantity of electric charge transported by a constant current of one ampere in one second. This standardization ensures consistency and accuracy in electrical measurements across various applications.
The concept of electric potential has evolved significantly since the early studies of electricity. Pioneers like Alessandro Volta and Michael Faraday laid the groundwork for understanding electric charge and energy. The term "volt," which is the SI unit of electric potential, was named in honor of Volta. The joule per coulomb emerged as a practical way to express electric potential, bridging the gap between energy and charge in electrical engineering and physics.
To illustrate the use of joules per coulomb, consider a simple circuit where a battery provides a voltage of 12 V (volts). If a charge of 2 C (coulombs) flows through the circuit, the energy transferred can be calculated as follows:
Energy (in joules) = Voltage (in volts) × Charge (in coulombs)
Energy = 12 V × 2 C = 24 J
This means that 24 joules of energy are available to move the 2 coulombs of charge through the circuit.
The joule per coulomb is widely used in electrical engineering, physics, and various applications involving electric circuits. It helps in determining how much energy is available for electrical work, making it essential for designing circuits, analyzing power systems, and understanding energy consumption in devices.

The Electronvolt per Elementary Charge (eV/e) is a unit of electric potential energy, representing the amount of energy gained by a single elementary charge (like an electron) when it is accelerated through an electric potential difference of one volt. This tool is essential for physicists, engineers, and students who are working with concepts in quantum mechanics, particle physics, and electrical engineering.
An electronvolt (eV) is defined as the amount of kinetic energy gained by an electron when it is accelerated through an electric potential difference of one volt. The elementary charge (e) is the charge of a single proton or the negative of the charge of a single electron, approximately equal to (1.602 \times 10^{-19}) coulombs.
The electronvolt is a standard unit of energy in the International System of Units (SI) but is often used in fields such as atomic and particle physics. The relationship between eV and other energy units, such as joules (J), is crucial for accurate calculations and conversions.
The concept of the electronvolt emerged in the early 20th century as scientists began to explore the properties of subatomic particles. As research in quantum mechanics and particle physics advanced, the electronvolt became a fundamental unit for measuring energy at microscopic scales, facilitating a deeper understanding of atomic interactions and energy levels.
To illustrate the use of the electronvolt per elementary charge, consider an electron that is accelerated through a potential difference of 5 volts. The energy gained by the electron can be calculated as follows:
[ \text{Energy (in eV)} = \text{Voltage (in V)} \times \text{Charge (in e)} ] [ \text{Energy} = 5 , \text{V} \times 1 , \text{e} = 5 , \text{eV} ]
The electronvolt is commonly used in various scientific fields, including:
To use the Electronvolt per Elementary Charge tool effectively:
1. What is the relationship between electronvolts and joules?
The relationship is given by (1 , \text{eV} = 1.602 \times 10^{-19} , \text{J}). This conversion is essential for translating energy values in different contexts.
2. How do I convert volts to electronvolts?
To convert volts to electronvolts, multiply the voltage by the elementary charge (1 e). For example, 10 volts equals 10 eV.
3. Why is the electronvolt important in physics?
The electronvolt is crucial for quantifying energy at the atomic and subatomic levels, making it a standard unit in fields like particle physics and quantum mechanics.
4. Can I use this tool for other types of charges?
This tool is specifically designed for elementary charges. For other charge types, adjustments may be necessary based on the charge's magnitude.
5. Is there a limit to the voltage I can input?
While there is no strict limit, extremely high voltages may not be practical for most applications. Always consider the context of your calculations.
