**About Electromotive Force Calculator (Formula)**

An Electromotive Force (EMF) Calculator is a tool that helps to calculate the Electromotive Force, which is the energy supplied by a source to move an electric charge from one point to another. Electromotive Force is measured in volts (V) and is commonly denoted by the symbol “E.”

**The formula to calculate Electromotive Force is:**

**E = W / Q**

Where E is the Electromotive Force in volts, W is the Work done in Joules, and Q is the Charge in Coulombs. In simple terms, the Electromotive Force is the ratio of the energy transferred by an electric circuit to the amount of charge that flows through it.

The Electromotive Force formula can be used in a wide range of applications, including electronics, electrical engineering, and physics. For example, it is used to calculate the voltage of a battery, the potential difference across a resistor or a capacitor, or the voltage of an electrical power source.

An Electromotive Force Calculator simplifies the process of calculating EMF by allowing users to input the values of Work and Charge, and automatically calculates and displays the result. This tool is helpful for students, researchers, and professionals who need to calculate EMF quickly and accurately.
