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.
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.
A difference in electrical charge from one point to another is measured in millivots is called?
The difference in electrical charge from one point to another measured in millivolts is called voltage. Voltage is a measure of the electrical potential difference between two points in a circuit and is responsible for the flow of electric current.
When is current produced?
Electric current is produced when there is a flow of electric charge in a circuit. This flow of charge is typically generated by a voltage source, such as a battery or power supply, which creates a potential difference that pushes the electrical charge around the circuit.
What voltage difference in an electrical circuit is best described as pontential?
The voltage difference between two points in an electrical circuit is best described as electrical potential difference. This represents the energy per unit charge required to move a charge between those points.
What is the relationship between current, charge, and velocity in an electrical system where the current is equal to the charge multiplied by the velocity?
In an electrical system where current is equal to the charge multiplied by the velocity, the relationship is that the current flowing through the system is directly proportional to both the amount of charge and the velocity at which the charge is moving. This means that as either the charge or the velocity increases, the current flowing through the system will also increase.
What is the relationship between voltage and charge in an electrical system?
Voltage is the measure of electrical potential difference between two points in a circuit, while charge is the amount of electric energy stored in an object. In an electrical system, the relationship between voltage and charge is that an increase in voltage leads to a greater flow of charge through the system. This is described by Ohm's Law, which states that the current flowing through a conductor is directly proportional to the voltage applied across it.
What is the term for the term potential difference in a charge between two points in a current path?
voltage
What is the difference in electrical charge between two regions on a nerve?
There is a slight difference in electrical charge between the inside and outside of a nerve cell membrane, known as the resting membrane potential. This potential is typically around -70 millivolts, with the inside of the cell more negative compared to the outside. This difference in charge is essential for the nerve cell to transmit electrical signals.
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 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.

Define the 'potential difference between the ends of a conductor'?
Potential difference between the ends of a conductor refers to the electrical energy difference per unit charge between two points in the conductor. It is commonly known as voltage and is measured in volts. A potential difference is necessary for the flow of electric current in a conductor.
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)
