For an eletric current to flow the only thing needed is for two objects to have a difference in charge?

Yes. However, depending on the size and shape of the objects, the amount of current that flows may be small and/or flow for only a brief time until the charges are neutralized. But - if the objects are connected to an electrical power source such as a battery or a wall plug, the charges are continuously supplied and the current continues to flow.

What is the difference between limiting current and diffusion current?
The limiting current is defined as the limiting value of a current that is approached as the rate of charge-transfer to an electrode is increased. The diffusion current is defined as a current in a semiconductor caused by the diffusion of holes and/or electrons.
How does the movement of charge affect the overall charge of objects?
It affects it by adding diversity to the objects nucleus and outer shell. It also produces a negative charge which focuses primarily on the Teflon don.

What is the shape of the graph between volt and electric charge where Volt is the potential difference between the ends of an ohmic resisitor and electric charge is the current flowing through it?
-- 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 the difference between volts and current?
Electrical current is the number of elementary charge units (coulombs) that pass by a given point in one second. Current, measured in amperes, is coulombs per second. Electrical voltage is the "pressure" behind that current. Voltage, measured in volts, is joules per coulomb.
For an electric current to flow the only thing needed is for two objects to have a difference in charge?
Actually, they need a difference in energy per charge. Voltage is energy per charge, in joules per coulomb, and a voltage differential is what is required to create an electric current flow.
Is it true for an electric current to flow only if two objects have a different charge?
Only if there is a potential difference between two points, does the charge move specifically in a direction.
The difference between charge and current?
Charge is potential, current is flowing.
Difference between electrical current and electrical charge?
current is the flow of charge.
What is an eletric current?
The time rate of flow of electric charge, in the direction that a positive moving charge would take and having magnitude equal to the quantity of charge per unit time: measured in amperes. See more.
When there is a difference in voltage the flow of charge is called?
flow of charge is called current. but the direction of flow of current is always taken oppsite to the flow of charge.
What is an eletric charge?
an electric charge is when 2 charges become together and the hit each other and dhen go home and sleeepppp zzzzz
What is the difference between current electricity and charge separation?
I have not found the answer to this question.
What is the difference between Current and Interference?
Current measures flow of charge. Interference is something that gets in the way.
Can potential difference ocur without current?
Yes. This is the build up of charge. The difference in charge, aka the potential difference, is the driving force that causes current to flow. The third law of thermodynamics is in action when the circuit is completed and the current flows between two point as a result of the potential difference between those two points. (p.s. I am an American girl)
