## Units of Voltage

## What is Voltage?

**Voltage, in physics, refers to the electrical potential difference between two points in a circuit or electric field. It represents the amount of energy transferred per unit charge as a charge moves between those points.**Voltage is a fundamental concept in electricity, driving the flow of electric current through conductors and determining the intensity of electrical circuits. It is typically measured in volts (V) and plays a crucial role in various electrical systems, from household appliances to complex industrial machinery, as well as in the generation, transmission, and distribution of electrical power.

## Formula of Voltage

The formula for voltage (V) is:

*V*=*W*/*Q*Where: 𝑉represents voltage (in volts, V)

𝑊 represents the work done or energy transferred (in joules, J)

𝑄 represents the electric charge (in coulombs, C)

## What are the Units of Voltage?

Voltage is measured in volts (V), representing electrical potential difference. It determines the flow of electric current in circuits. Common units include millivolts (mV) and kilovolts (kV). Voltage is essential in powering electrical devices and systems.

## SI units of Voltage
