Electromotive Force (Noun)
Meaning
The rate at which energy is drawn from a source that produces a flow of electricity in a circuit; expressed in volts.
Classification
Nouns denoting natural phenomena.
Examples
- The electromotive force of the battery caused a current to flow through the circuit.
- A higher electromotive force is required to drive the current through a circuit with greater resistance.
- In a closed circuit, the electromotive force of the power source must be balanced by the sum of the voltage drops across each component.
- The definition of electromotive force, measured in volts, is the energy available to drive 1 amp of current through a circuit.
- Every battery has an intrinsic electromotive force, which declines as the battery discharges.
