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.

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.
What is the relationship between voltage and electric potential energy difference?
Voltage is a measure of the electric potential energy difference between two points in an electric field. The greater the voltage, the greater the electric potential energy difference between the two points.
Is potential difference directly or inversely proportional to resistance?
Potential difference is directly proportional to resistance according to Ohm's Law. This means that as resistance increases, the potential difference across a component also increases, assuming the current remains constant.
What is the relationship between voltage, potential difference, and electrical energy in a circuit?
Voltage, also known as potential difference, is the force that drives electrical current in a circuit. The higher the voltage, the greater the potential difference and the more electrical energy is transferred in the circuit.
What is the difference in electric potential between two points?
The electric potential difference between two points is the work done per unit charge in moving a charge from one point to the other. It is measured in volts (V) and represents how much energy is needed to move a charged particle in an electric field. The greater the potential difference, the greater the force that would be exerted on a charged particle moved between the points.
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.
What are the differences between potential difference and emf?

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 statement describes the potential energy diagram of an exothermic reaction?
The difference in potential energy between the reactants and products.
What is the difference in electric potential between two points?
The electric potential difference between two points is the work done per unit charge in moving a charge from one point to the other. It is measured in volts (V) and represents how much energy is needed to move a charged particle in an electric field. The greater the potential difference, the greater the force that would be exerted on a charged particle moved between the points.
What is the relationship between the potential difference and the motion of a charged particle in a uniform electric field?
The potential difference in a uniform electric field affects the motion of a charged particle by determining the direction and speed of its movement. The greater the potential difference, the stronger the force on the charged particle, leading to faster motion in the direction of the field.
What is the potential difference in electricity?
Potential difference, also known as voltage, is the force that drives the flow of electric current in a circuit. It is measured in volts and represents the energy per unit charge available to a charge to move in an electric field. A higher potential difference leads to a greater flow of current in a circuit.
