Supply voltage

Supply voltage (also called source voltage or supply voltage) is the electrical voltage that is supplied from an electrical source to an electrical circuit or device. This voltage represents the electrical potential or potential difference between two points in the circuit and drives the movement of electric current through the circuit.

Definition of supply voltage:

Supply voltage is the electrical voltage that is available to drive electrical devices or circuits and provides the electrical current that enables the functionality of these devices.

The unit of supply voltage in the International System of Units (SI) is the volt (V). The supply voltage can be constant (for example, in the case of battery power) or it can change over time (for example, in the case of AC power from the mains).

Supply voltage is essential to the operation of electrical devices and circuits because it creates the potential for the movement of electrons through conductors and allows the transfer of electrical energy from an electrical source to devices that perform certain tasks. Different electrical equipment and components have specific requirements for supply voltage, so it is important to comply with these requirements for the proper operation and safety of electrical systems.
