Final answer:
Yes, the statement is true. 'Voltage' is widely used as a common term for 'potential difference' and is preferred for being more descriptive and recognizable.
Step-by-step explanation:
The statement 'Voltage is the common word for potential difference' is true. The term voltage is often used interchangeably with potential difference because it is more user-friendly and is widely recognized in common discourse. However, voltage technically refers to the potential difference between two points in an electric field, which prompts an electric current to flow in a closed circuit. The term potential difference is more descriptive, as it specifically denotes the difference in electrical potential between two points.
