-- If one axis of your graph represents the current flowing through the resistor,
then label it "Current", not "Electric charge". There's a big difference between
charge and current.
-- Ideally, the current through an ohmic resistor is a linear function of the voltage
across its ends, namely a direct proportion with the resistance being the constant
of proportionality.
-- Ideally, the graph is a straight line, with slope equal to the resistance in ohms,
and y-intercept of zero.
-- In reality, the resistor dissipates energy at the rate of (voltage) x (current) watts.
It must warm up as a result, and the change in its temperature always has some effect
on its ohmic resistance.

What is a difference in electric charge called?
The chemical gradient refers to the imbalance of substances across the membrane. The Electrical Gradient refers to the difference of charges between substances on different sides of the Membrane. The Electrochemical Gradient refers to the combination of the previous two gradients. The short answer is MEMBRANE POTENTIAL.
What is potential step from 1 potential to o potential?
When there is a potential difference between two points, such as from 1 potential to 0 potential, it means that there is a voltage drop of 1 unit in the direction from higher potential to lower potential. This difference in potential creates an electric field that can drive the flow of electric charge.
Potential difference between -1 and 2 volts?
The potential difference between -1 and 2 volts is 3 volts. A potential difference of 3 volts means that there is an electric field pushing a charged particle from the -1 volt point to the 2 volt point.
What is the definition of voltage?
Difference in potential between two points. Like the voltage of an energizer AA battery is 1.5 volts BETWEEN its terminals. If you place two AA batteries in a flashlight, the voltage of the series combination of AA batteries from one tip to the other is now 3 volts.
What is potencial difference measured in?
The unit of measure is the Volt Potential difference is basically electrical "pressure" (an excess of electrons). Volt.....The unit of electric potential. Named after the Italian physicist Alessandro Volta (1745- 1827). The potential difference is the difference in charge at the poles of a current source The volt (symbol: V) is the SI derived unit of electromotive force, commonly called "voltage". It is also the unit for the related but slightly different quantity electric potential difference (also called "electrostatic potential difference"). ... en.wikipedia.org/wiki/Volt
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 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 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.

What is the relationship between the electric field between two plates and the potential difference across them?
The electric field between two plates is directly proportional to the potential difference across them. This relationship is described by the equation E V/d, where E is the electric field, V is the potential difference, and d is the distance between the plates.
What is the relationship between voltage (e), electric potential difference (v), and distance (d) in an electric field?
In an electric field, the relationship between voltage (e), electric potential difference (v), and distance (d) is described by the equation v e d. This means that the electric potential difference (v) between two points in an electric field is equal to the product of the electric field strength (e) and the distance (d) between the points.
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 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 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 is the relationship between electric potential, voltage, and the concept of electric potential energy?
Electric potential, also known as voltage, is a measure of the electric potential energy per unit charge at a point in an electric field. The relationship between electric potential, voltage, and electric potential energy is that electric potential is the potential energy per unit charge, and voltage is the difference in electric potential between two points. Electric potential energy is the energy stored in a system of charges due to their positions in an electric field, and it is related to the electric potential by the equation: Electric Potential Energy Charge x Electric Potential.
Why the potential difference between head and tail of an electric cel is 600V?
The potential difference of 600V between the head and tail of an electric cell is due to the chemical reactions occurring within the cell which generate an imbalance of electrons. This creates an electric field within the cell that results in the potential difference. The specific design and composition of the cell determine the amount of potential difference it can produce.
