What is the Difference between current and current density?
Electric current is the rate of [http://hyperphysics.phy-astr.gsu.edu/hbase/electric/elecur.html#c2 charge] flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes through any cross sectional area,which can be measured by Pi*r*r. [1coulomb/second=1Ampere]while Electric current density is the measure of electric charges passing through a conductor in a electric circuit in a constant cross sectional area of 1 meter square.[1Ampere/Meter square]
What is the unit of electron current?
Electron current flow is measured in coulombs per second, which is known as amperes. A coulomb is about 6.242 × 1018 electrons.
What term is used to indicate rate of current flow in a circuit?
AmperesAnother AnswerThere really is no such thing as a 'rate of current flow'; if it existed, then it would be expressed in amperes per second.
In which circuit does charge reverse direction many times per second?
In an alternating current (AC) circuit, the electric charge periodically reverses direction at a certain frequency. This is in contrast to a direct current (DC) circuit, in which charge flows in one direction only.
What are the units of electrical capacitance?
The unit of capacitance is the farad. One farad requires one ampere to sustain one volt per second... dv/dt = i/c ...where volts per second is proportional to current in amperes and inversely proportional to capacitance in farads.
What are electrical currents measured in?
Electric current is measured in amperes. 1 ampere = 1 coulomb/second
What is the unit of measurement for electrical flow rate?
That would be the current. The international unit for electrical current is the Ampere. Spelt ampere (with a lower case "a"). The abbreviation is given the upper case "A".
What is the unit used to measure electric flow?
The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulombper second.
What is the name for the flow of electrons in an electric circuit?
A flow of electrons in an electrical circuit is called a current, which is the name given to the amount of electrical charge flowing in a certain period of time.Any total quantity of electrical charge is measured in coulombs.Any flow of electrical current is measured in amps.1 amp is equal to a flow of 1 coulomb of electrical charge in one second of time.
What is an eletric current measured in?
If you refer to the units, power (any power, not just electrical power) is energy divided by time. The SI unit is the watt, equal to 1 joule/second.
What is meant by the terms electric current?
Current is the amount of electrical charge that flows past a given point in a given time. Current is measured in Amperes, which is Coulombs per Second. Sometimes, erroneously, we use the term current to refer to voltage or power. Voltage is Joules per Coulomb. Power is Joules per Second, or Voltage times Current.
What can electric current be measured by?
Electric current is measured in amperes. 1 ampere = 1 coulomb/second
What describes the volume of electrical current?
Electric current is described in units of 'Amperes' . It's a direct expression of the number of electrons that pass a point in the circuit every second. "1 Ampere" is something like 6,250,000,000,000,000,000 electrons per second.
What is a Henry?
A henry is the unit of electrical unductance, the inductance induced in a circuit by a rate of change of current of one ampere per second.
Th flow of an electrical current be?
The flow of an electrical current be -- Coulombs per Second or Ampere hours per hour.
What does a coulomb measure?
A coulomb is a unit of electrical charge. It is the charge that passes a point in an electrical circuit in one second when a current of 1 ampere is flowing through the point.
How long is 1 gigahertz?
A 'Hertz' is a change in electrical state. It is measured over one second. 'Giga' is referring to 10^9 or one billion. A Gigahertz is a frequency change of one billion Hertz in one second. Electrical current that is commonly called 'alternating current' (AC) ranges from 50 to 60 Hertz at 110 to 220 Volts.
