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 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.
How does the movement of charge affect the overall charge on objects?
The movement of charge can alter the overall charge on objects by redistributing the charges. For example, if electrons are transferred from one object to another, the object that loses electrons becomes positively charged while the one that gains electrons becomes negatively charged. This movement of charge creates an imbalance in the overall charge of the objects.
The buildup of electrons in a cloud is a form of current electricity?
The buildup of electrons in a cloud is not a form of current electricity. Current electricity refers to the flow of electrons along a conductive path, while the accumulation of charge in a cloud generates an electric potential that can lead to lightning discharge when the charge difference becomes large enough.
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.
Does amps express the difference in energy?
No, amps (amperes) do not directly express the difference in energy. Amps measure electrical current, which is the flow of electric charge. Energy is typically measured in units such as joules or kilowatt-hours.
Is it true for an electric current to flow only if two objects have a different charge?
No, electric current flows due to the movement of charged particles, usually electrons. Two objects with the same charge can still have current flow between them if there is a potential difference (voltage) present.
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.
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.
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
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 the term for the term potential difference in a charge between two points in a current path?
voltage
What is the difference between Current and Interference?
Current measures flow of charge. Interference is something that gets in the way.
What is the difference between gravitational and electrostatic forces in terms of their effects on objects?
Gravitational forces are based on mass and pull objects towards each other, while electrostatic forces are based on charge and can attract or repel objects based on their charge.
What constitutes an electric current in a wire?
An electric current in a wire is the flow of electric charge, typically carried by electrons, through the wire. This flow of charge is driven by a voltage difference, or potential difference, between two points in the wire.
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)
What is the term for the potential difference in a charge between two points in current path?
capacitance
