What is the term for the difference in voltage between two points in an electrical circuit?

The term used to describe the difference in voltage between two points in an electrical circuit is known as potential difference. This concept is fundamental in understanding how electrical energy is transferred in circuits.

Potential difference indicates how much work needs to be done to move a charge from one point to another in the circuit. It is measured in volts and is critical for defining how electrical devices operate; a greater potential difference typically results in a greater current, assuming resistance remains constant according to Ohm’s law.

Recognizing the term "potential difference" is crucial because it forms the basis for many circuit calculations and principles, such as those involving energy transfer and electrical safety. Understanding this concept enables individuals to analyze and design circuits effectively, ensuring they can evaluate the behavior of electrical systems accurately.
