Difference between voltage and current?
Voltage is electrical potential, measure in derived units of volts, which is joules per coulomb. Current is electrical flow, measured in derived units of amperes, which is coulombs per second. Stated in other terms, voltage is energy per charge, while current is charge per time. That makes power, or watts, equal to energy per time, and that is joules per second.If you think of the water system analogy, volts is sort of similar to pounds per square inch (though not completely so), while amperes is similar to gallons per minute.AnswerVoltage is synonymous with 'potential difference' -not potential- measured in volts. Current is the flow of electrical charge, measured in amperes. The volt is an SI derived unit, wheras an ampere is an SI base unit.
What is the relationship between time charge and current?
Yes current = charge / time = I = Q/t
What is the difference between charge and current?
An electric charge can be either negative or positive. The smallest quantity of negative charge is the amount represented by one electron, and this is exactly equal to the amount of positive charge represented by one proton. In practice, charge is measured in coulombs (C). Normally, atoms have identical numbers of protons and electrons, so atoms are normally neutral. Atoms that are charged are called 'ions'. A 'positive ion' has an overall positive charge, which means it has more protons than electrons. A 'negative ion' has an overall negative charge, which means it has more electrons than protons. 'Free electons' are negatively-charged sub-atomic particles that have become detached from an atom. Most metals have an abundance of free electrons, and it is a drift of these free electrons that constitute an electric current. In electrolytes (conducting fluids) a current is usually a movement of positive or negative ions. In both cases, an electric current is a drift of electrical charge. An electric current is measured in amperes (A). The ampere is an SI base unit, and defined in terms of the force between parallel, current-carrying conductors, due to their magnetic fields. A coulomb is an SI derived unit, defined in terms of current and time, as an ampere second.
A coulomb is a measure of whereas an ampereis a measure of?
A coulomb is a unit for measurement of electrical charge and an ampere is the unit used for measurement of electric current.
Why current a fundamental quantity though it is flow of charge per unit time?
Ampere = Coloumb / second is the same as saying that Coloumb = Ampere x second. Any of the two electrical units can be derived from the other one. Ampere is NOT a "fundamental quantity"; it is an SI base unit. The base units are not necessarily those that are somehow considered more "fundamental" than others; instead, the base units are those that can be measured with a great accuracy. In the case of current vs. charge, it seems that measuring a current can be done with greater accuracy than measuring a charge directly; therefore, the current is the base unit, and the current is derived. However, this doesn't make current any more "fundamental" than charge.
The difference between charge and current?
Charge is potential, current is flowing.
What is the difference between electrical force and charge?
Electrical force actually acts on electrical charges.
What is the difference in electrical charge between two regions on a nerve?
potential difference- robbert bashouri
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 the electrical charge is created?
An electrical current
An electrical charge in motion called?
An electrical charge in motion is called a current.
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 electricity?
The word Current is a term used to describe the characteristics of electricity, the same way voltage and resistance are used. As an example: voltage is a difference in potental and is often considered the amount of pressure pushing an electrical charge or certain number of electrons through a conductor. This electrical charge is called current. Any conductor has resistance to the flow of charge or current. If for example a conductor has a resistance of 2 ohms and a voltage of 12 volts is applied the resulting current flowing in the circuit can be measured to be 6 ampere..the unit for current. Current is therefore, considered the intensity or amount of charge.Electricity then is the movement of this current of charge The word Current is a term used to describe the characteristics of electricity, the same way voltage and resistance are used.

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 electric currents and electric charge?
Electric current is a flow of electrons is a measure of the quantity of electrical charge passing any point of the wire in a unit time.And, electric current is measured in ampere (A).Whereas, electric charge is the quantity of electricity that flows in electric currents . And , it is measured in coulomb (C)
What is difference Between energy and charge?
In my opinion charge relates to only electrical parameter while as energy can be electrical, mechanical ,chemical or otherwise. Viraj Gurjar virajgurjar@yahoo.com
What is moving electrical charge called?
