Answer:
A single volt is the standard unit of measurement for electric potential difference or voltage in the International System of Units (SI). It is defined as the amount of electric potential difference that is required to move a charge of one coulomb between two points in an electric circuit, while doing one joule of work.
Step-by-step explanation:
In practical terms, a single volt is a relatively small amount of electrical potential difference, and it is commonly encountered in everyday electrical devices such as batteries, power supplies, and electrical outlets. For example, a typical household electrical outlet in the United States delivers an alternating current (AC) voltage of around 120 volts, while the voltage of a small battery such as a AA or AAA cell is typically around 1.5 volts.
In summary, a single volt is a unit of measurement for electric potential difference that is used to quantify the amount of electrical energy that is available to do work in an electric circuit.
