What is the relationship between EMF and potential difference in an electrical circuit?
The relationship between EMF (electromotive force) and potential difference in an electrical circuit is that EMF is the total energy supplied by a source, while potential difference is the energy transferred per unit charge as it moves through the circuit. In simpler terms, EMF is the total push provided by the power source, while potential difference is the push experienced by the charges as they flow through the circuit.
Can the potential difference across a battery be greater than its EMF?
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.
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 difference between electrical potential and electromotive force?
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.
Is potential difference always less than emf of the cell?
No. Because during charging process of a battery current flows in opposite direction to the discharging/consumption. so equation Emf=P.d. +Ir is changed to Emf=p.d. +Ir. Hence during charging process of a battery Potential difference is greater than electromotive force.

Difference between voltage and emf?
'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.
Another name for EMF?
"Potential difference" or "Voltage".
Why volt meter is always placed in parallel?
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.
What is the potential difference between two points in a circuit is called?
Voltage drop
When is the terminal potential difference of a battery greater than its emf?
When it is being loaded.
Can the potential difference across a battery be greater than its EMF?
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.
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 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.
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.
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 unit would be used to measure the potential difference between two poles of a battery?
The volt.The volt.The volt.The volt.
