'Voltage' is simply another term for 'potential difference', and an electromotive force is the open-circuit, or no-load, potential difference of a source such as a battery or generator.

"Potential difference" or "Voltage".


What are the differences between potential difference and emf?

Potential difference is the difference in electric potential energy between two points in a circuit, while electromotive force (emf) is the total energy provided per unit charge by a battery or voltage source. In other words, potential difference measures the voltage drop across a component in a circuit, while emf represents the energy per unit charge supplied by the source.


Difference between back EMF and induced EMF?

An induced electromotive force (emf) is an induced voltage. Voltage (emf) causes current flow, and this induced voltage will cause a current that is called the induced current.We might also add that the induced current will cause a magnetic field to expand about the current path, and this field will "sweep" the conductor. The sweeping of the conductor by that expanding magnetic field will set up an emf that will oppose the emf that was creating it.CommentTechnically, there is no such thing as an 'induced current'. It is voltage that is induced. Any current flows as a result of that induced voltage being applied to a load. But that current is certainly NOT induced!


It can be said that pressure and electromative force are the same?

There is analogy between pressure and EMF or voltage. What pressure is to the liquids, EMF or voltage is to electric current. But, of course, they are not the same.


A device that provides an emf?

EMF (short for "electromotive force" - not a well-chosen name, since it isn't exactly a force) is more properly called a "voltage". A device that provides that can be a battery, or you can get the voltage from the outlets in your home.


What symbol is used to measure potential difference?

V which abbreviates the word volt, which is the unit of measure of the difference in electromotive force (EMF), (or electric potential) between two points of contact; the resulting voltage difference could be direct current (DC) or alternating current (AC) depending on the source of the voltage difference.


Can terminal potential difference be greater than the emf supplied?

No, the terminal potential difference cannot be greater than the emf supplied. The emf represents the maximum potential difference that the cell or battery can provide, while the terminal potential difference is the actual potential difference across the terminals when a load is connected.


What is the term for he phenomenon of emf development between two different metals placed in contact?

The term for the phenomenon of emf development between two different metals placed in contact is called the thermoelectric effect. This effect occurs because of the temperature difference between the two metals, which creates a potential difference or voltage.


What are the differences between emf and voltage drop?

emf and voltageAnswerElectromotive force is the potential difference created by a source, such as a battery or generator, when it is not connected to a load -in other words, on 'open circuit'.Voltage drop is the potential difference across a load, such as a resistor, which causes current to flow through that load.A voltage drop occurs, internally, in batteries and generators, when they are supplying a load. The battery or generator's terminal voltage, when supplying a load, is its e.m.f. less its internal voltage drop.


Another word for voltage?
