Another term for voltage is _______.

Voltage is often referred to as electromotive force (emf), which emphasizes its role in driving electric current through a circuit. Electromotive force is a measure of the energy provided per charge by a power source, such as a battery or generator, and is crucial for understanding how electrical systems function. This term highlights the potential difference in electric potential energy between two points in an electrical circuit, which is a key concept in the study of electricity. In practical terms, when voltage is applied across a load, it causes current to flow, enabling the operation of various electrical devices. Understanding voltage as electromotive force helps students grasp the fundamental principles of electricity and the behavior of circuits.
