2. A locomotive operated by electric power picked up from a system of continuous overhead wires, or, sometimes, from a third rail mounted alongside the track.
2. An instrument that converts electrical power into mechanical torque or the force generated by an internal-combustion engine to turn a vehicle's drive shaft.
2. A mechanical action, motion, or force produced by an electric current.
2. Relating to or producing an electric current or electric action.
3. A reference to the passage of electricity in a current or a motion produced by it.
2. The electric potential, or ability of electric energy to perform work.
Electromotive force is usually measured in joules per coulomb, or volts; and the higher the voltage, the greater the potential of electric energy.
Any device; such as, a storage battery, that converts some form of energy into electricity is a source of electromotive force or EMF or emf; or, a generator produces an electromotive force.3. The difference in electric potential, or voltage, between the terminals of a source of electricity; such as, a battery from which no current is being drawn. When current is drawn, the potential difference drops below the emf value.
4. The force that causes a flow or the movement of electrons through an electrical circuit.
It is the amount of energy derived from an electric source in one second when one unit of current is passing through the source, commonly measured in volts.
Electromotive force is produced by differences in electrical charge or potential.5. Energy per unit electric charge that is imparted by an energy source; such as, an electric generator or a battery.
When the device does work on the electric charge being transferred within itself, energy is converted from one form to another.
2. A serial arrangement of metallic elements or ions according to their electrode potentials determined under specified conditions; the order shows the tendency of one metal to reduce the ions of any other metal below it in the series.
3. A series in which the metals and other substances are listed in the order of their chemical reactivity or electrode potentials, the most reactive at the top and the less reactive at the bottom.
4. A tabulation on which various substances; such as, metals or elements, are listed according to their chemical reactivity or standard electrode potential.
It is usually ordered with increasing standard electrode potentials (most negative on top).
For metals, the order indicates the tendency to spontaneously reduce the ions of any other metal below it in the series.
During electrolytic reduction of cations (for example, electroplating) an element lower in the series (more positive) will deposit first, and an element higher in the series (more negative) will deposit only when the solution is practically depleted of the ions of the first element.
In New York City, he installed the world's first central electric power plant (1881-1882).
2. A motor run by electricity.
2. A control circuit used to change or to vary the speed of a direct-current (DC) motor operated from an alternating-current (AC) power line.
Silicon controlled rectifiers or power transistors rectify or correct the voltage and vary the field current of the motor.
