What is the change in the potential energy of a single electron as it moves through the light bulb?
As an electron moves through a light bulb, its potential energy changes due to interactions with the electric field. This change in potential energy is converted into light and heat energy, which powers the light bulb.
What is the relationship between electric potential scalar and the concept of work done in moving a unit positive charge from one point to another in an electric field?
The electric potential scalar is a measure of the electric potential energy per unit charge at a point in an electric field. The concept of work done in moving a unit positive charge from one point to another in an electric field is related to the change in electric potential between the two points. The work done is equal to the change in electric potential multiplied by the charge being moved.
What is the relationship between the electric potential energy of a system and another physical quantity?
The electric potential energy of a system is directly related to the charge and the distance between the charges in the system. As the charges or the distance change, the electric potential energy of the system also changes accordingly.
What is the relationship between electric potential and electric field in a given system?
In a given system, the electric potential is directly related to the electric field. The electric field is the rate of change of electric potential with respect to distance. In other words, the electric field points in the direction of decreasing potential.

If potential is constant throughout a given region of space can you say that electric field is zero in that region?
No, the electric field does not necessarily have to be zero just because the potential is constant in a given region of space. The electric field is related to the potential by the gradient, so if the potential is constant, the electric field is zero only if the gradient of the potential is zero.
Which physical property is defined as the ratio of the change in an electric charge in a system to the corresponding change in its electric potential?
The physical property defined as the ratio of the change in an electric charge in a system to the corresponding change in its electric potential is capacitance. This property is measured in farads (F) and it quantifies how much charge can be stored per unit voltage.
How does the increase or decrease of potential difference affect the flow of the electric current?
Increase or decrease in potential results in the change in direction of the flow of electric current.
What is the relationship between the electric potential in a field and the work done in moving a charge within that field?
The electric potential in a field is directly related to the work done in moving a charge within that field. The electric potential represents the amount of work needed to move a unit positive charge from one point to another in the field. The work done in moving a charge within the field is equal to the product of the charge and the change in electric potential between the two points.
What is the relationship between the electric potential and electric field according to the equations V kq/r and E kq/r2?
The relationship between electric potential (V) and electric field (E) is that the electric field is the negative gradient of the electric potential. This means that the electric field is the rate of change of the electric potential with respect to distance. The equations V kq/r and E kq/r2 show that the electric field is inversely proportional to the square of the distance from the charge, while the electric potential is inversely proportional to the distance from the charge.
What is the definition of electric gradient?
the rate of change of maximum value of potential with respect to distance is known as potential gradient
What happens to the potential energy of a stationary charge when it begins to move freely from one point to another under the influence of an electric field?
The potential energy of the particle goes down just as its kinetic energy, which results from the particle's increasing motion, increases - thereby conserving the total energy of the system. Of course these terms refer ONLY to the potential energy due to the charged particle's presence in an electric field and its change in motion in the direction of that field. If there were also a gravitational field present and the particle had mass, it would have also have potential (and kinetic, if it's falling too) energy from that field, independently of the electric field.
