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.
Yes, the potential difference across a battery can be greater than its EMF when the battery is connected in a circuit and current is flowing through it. This can happen due to internal resistance within the battery that causes a voltage drop.
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.
Electrical potential refers to the electric potential energy per unit charge at a point in an electric field, measured in volts. Electromotive force (emf) is the energy per unit charge supplied by a source of electrical energy, such as a battery, to drive current through a circuit, also measured in volts. Essentially, electrical potential is a property of a point in the field, while emf is the force that drives the flow of charge.
Yes, potential difference across a cell is typically less than the electromotive force (emf) of the cell due to internal resistance and other factors affecting the flow of electric current. The emf represents the maximum voltage a cell can provide, while the potential difference takes into account the voltage drop caused by these internal resistances.
Voltage: This measures the electric potential energy between two points in a circuit. Electromotive force (EMF): It represents the push that drives the electric current in a circuit. Potential difference: This is the difference in electric potential between two points in a circuit, causing the flow of current.
'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".
Because the quantity it measures is 'EMF' or 'potential difference', that is,the difference in potential between two points. There may be 1 or 1,000circuit components between the two points.

When it is being loaded.

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.
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.
The volt.The volt.The volt.The volt.
"The potential difference between the terminals of a battery will equal the emf of the battery when there is no current in the battery. At this time, the current though, and hence the potential drop across the internal resistance is zero. This only happens when there is no load placed on the battery-that includes measuring the potential difference with a voltmeter! The terminal voltage will exceed the emf of the battery when current is driven backward through the battery, in at its positive terminal and out at its negative terminal."
