Can terminal potential difference be greater than the emf supplied?

All cells have internal resistance. When connected to a load, the resulting load current results in an internal voltage drop across the internal resistance. This voltage drop acts in the opposite sense to the cell's e.m.f., thus causing its terminal voltage to fall below that of the e.m.f. The greater the load current, the greater the difference between the terminal voltage and the e.m.f.

Is potential difference directly or inversely proportional to resistance?
Potential Difference (V) across two resistors is directly proportional to the resistance (R) as greater the potential difference, greater is the resistance and vice versa.
What are the differences between potential difference and emf?
emf is present mainly in battery and potential difference is mainly present in circuit. emf is greater than p.d and p.d is greater than emf.......the units of both are Volt.....
Which is greater - the terminal velocity of a small blood droplet or the terminal velocity of a large blood droplet?
The small blood droplet would have a greater terminal velocity. The smaller droplet has a smaller surface area, thus suffers less air resistance.
Why is potential energy greater than kinetic energy?
It isn't so. Potential energy can be greater, or less, for a given object, depending on its position and its speed.
Is itTrue or false is the greater the height of an object the greater its gravitational potential energy?
true
When is the terminal potential difference of a battery greater than its emf?
When it is being loaded.
How can you get the largest voltage difference?
There is no such thing as a 'voltage difference'! 'Voltage' means 'potential difference', so what you appear to be asking is "How do you get the largest potential difference difference?'! Potential difference is caused by the separation of charges between two points. The greater the amount of charge separation, the greater the potential difference.
Is potential difference directly or inversely proportional to resistance?
Potential Difference (V) across two resistors is directly proportional to the resistance (R) as greater the potential difference, greater is the resistance and vice versa.
What statement describes the potential energy diagram of an exothermic reaction?
The difference in potential energy between the reactants and products.
What are the differences between potential difference and emf?
emf is present mainly in battery and potential difference is mainly present in circuit. emf is greater than p.d and p.d is greater than emf.......the units of both are Volt.....
What is difference between a Schedule III controlled substance and a Schedule II?
greater potential for addiction
What happens to the terminal velocity if the weight is greater?
Other things (the volume and shape) being equal, a greater weight would cause a greater terminal velocity.
What is potential difference or voltage?
If you take two different nodes in a network and if you find the difference in voltage for those nodes then it is known as potential or voltage difference. Here the reference is not taken. But if you find potential difference between a node and its respective ground it is known as voltage at that node here reference is ground potential i.e zero.Answer'Voltage' is synonymous with 'potential difference'; they both mean the same thing. And it is important that these terms are not confused with 'potential'. So, it is incorrect to say 'voltage difference' (which would mean 'potential difference difference'!), or to describe a voltage as existing 'at' a particular point, or 'with reference to', for example, earth or ground.In very simple terms, if two points are at different potentials, then there is a potential difference (or 'voltage') between them. A potential exists when work is done moving a charge to a particular point; the greater the work, the higher the potential. 'Potential' is roughly equivalent to the potential energy gained by an object when it is lifted against the force of gravity.Think of it this way: 'potential' is equivalent to 'height', whereas 'potential difference' (voltage) is equivalent to the difference between points at different heights.
How does an object affect the height of the object?
Directly. The greater the potential fall, the greater the potential energy.
Why is the terminal velocity in water less than the terminal velocity in air?
More resistance, caused by a greater density.
When quantity supplied is greater than quantity demanded there is?
Excess supply.
If quantity demanded is greater than quantity supplied?
it is called a shortage
