Potential Difference (p.d) in an electric circuit is the measurement of energy transfer per unit charge in volts (v) or joules per coulomb (JC^-1). However, in contrast to the Electromotive Force (emf) in a circuit, which is a component that adds charge to the current (usually a cell). p.d uses up the charge to power a component eg a lamp. We would express this as the potential difference across the lamp. We can also say pd (v) = workdone (W)/ charge (Q). because the transfer of energy is the work done and this is per unit of charge.
Example.
What is the pd through a lamp where we have 4 coulombs of charge passing through it and transferring 48 joules of electrical energy into heat and light.
V=W/Q
pd=48/4 =12v

Why is thermoplastic not suitable for making an electric light switch?
Because it can be melted and melted again
What is a bus fault?
When a fault occurs in the electric bus (electric lines and intersections) due to short circuit between the phases or between 1 or more phase and ground, the current value mounts up to a very high value, which is known as bus fault current. This high value of current may cause damages to the transformers and could also rupture the other electric lines connected to the bus.
What is the difference between electrical potential energy and potential difference?
Electric potential is the electric potential energy per unit coulomb. So unit for electric potential is J/C and that of electric potential energy is simply J
What Electric potential or potential difference?
Electric potential (also known as voltage) is the amount of electric potential energy per unit of charge at a specific point in an electric field. It is measured in volts (V) and determines the ability of a charge to do work. Potential difference is the difference in electric potential between two points in an electric field and is responsible for the flow of electric current between those points.
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.
What is the dimension of potential difference?
The dimension of potential difference is voltage, which is measured in volts (V). Voltage represents the difference in electric potential energy per unit charge between two points in an electric circuit.
What is the difference between voltage and electric potential, and how do they relate to each other in an electrical circuit?
Voltage is the measure of the electric potential difference between two points in an electrical circuit, typically measured in volts. Electric potential, on the other hand, refers to the electric potential energy per unit charge at a specific point in the circuit. In simpler terms, voltage is the potential difference between two points, while electric potential is the potential energy at a single point. In an electrical circuit, voltage is used to describe the potential energy difference that drives the flow of electric current from one point to another.
what is the name of the device that is used to maintain the electric potential difference?
The device used to maintain electric potential difference is called a voltage source, such as a battery or generator.
What condition is necessary for electric charge to flow?
For electric charge to flow, there must be a potential difference (voltage) between two points in a conducting material. This difference in potential creates an electric field that exerts a force on the charges, causing them to move. Without a potential difference, charges will not flow.

What is the definition of potential defference?
Potential difference is the difference in electric potential between two points in an electric field. It is measured in volts and represents the work done per unit charge in moving a test charge between the two points.
How is electric potential generated in a conductor during the flow of charges?
Electric potential in a conductor is generated by the movement of charges, creating an electric field. As electrons flow through the conductor, they experience a resistance, which causes a potential difference to develop. This potential difference creates an electric field that drives the flow of charges.
What is the difference between electric potential energy and electric potential, and how can we distinguish between the two concepts?
Electric potential energy is the energy stored in an electric field due to the position of charged particles, while electric potential is the amount of electric potential energy per unit charge at a specific point in the field. The key difference is that electric potential energy is a form of energy, while electric potential is a scalar quantity that represents the potential energy per unit charge. To distinguish between the two concepts, remember that electric potential energy is measured in joules, while electric potential is measured in volts.
What kind of difference is measured in volts?
Volts are a measure of electric potential difference.
