# Describe voltage, including its unit of measurement and symbol(s).

## Definition

Description should include- defining
*voltage*as the potential difference in charge between two points in an electrical field used to push the electrons through the circuit - identifying that voltage is always expressed between two points in an electrical field
- providing examples for voltage produced by alternative methods
- identifying that the unit of voltage is measured in volts (Volts)
- identifying the symbols for voltage (V) and (E).

## Process/Skill Questions

- What is the unit of measurement for voltage?
- What letter symbol is used to represent voltage?
- What are some alternative voltage sources?
