what is electrical current?

Answer 1

Electric current is the flow (movement) of electric charge. The SI unit of electric current is the ampere (A), which is equal to a flow of one coulomb of charge per second
In solid conductive metal, a large population of electrons are mobile or "free" electrons. These electrons are bound to the metal lattice but not to any individual atom. Even without an external electric field applied, these electrons move about randomly due to thermal energy but on average, there is zero net current within the metal. Given an imaginary plane through which the wire passes, the number of electrons moving from one side to the other in any period of time is exactly equal to the number passing in the opposite direction
When a metal wire is connected across the two terminals of a DC voltage source such as a battery, the source places an electric field across the conductor. The moment contact is made, the free electrons of the conductor are forced to drift toward the positive terminal under the influence of this field. The free electron is therefore the current carrier in a typical solid conductor. For an electric current of 1 ampere rate, 1 coulomb of electric charge (which consists of about 6.242 × 1018 electrons) drifts every second through the imaginary plane through which the conductor passes.

What Is Current

Answer 4

When some electric charge flow on a electrical wire which is connected on a electric ckt is called electrical current.

Answer 5

An electron is an extremely tiny particle. In a single second, a vast number of electrons will pass by any point in a circuit.
The quantity of electron flow or the 'Quantity of Electricity' ('Q'), is measured in units called 'Coulombs' ('C').

One Coulomb represents 6.24 x 10^18 electrons. (6.24 million, million, million ).

1 Coulomb is defined as : -
"The Quantity of Electricity conveyed in One Second by a Current of One Ampere"
The 'Rate' at which electricity flows (the 'Current'), Symbol 'I', is measured in 'Amperes', Symbol 'A' ( Amp ).

"A Current of 1 Amp flows in a Conductor when 1 Coulomb passes a given point in 1 second".

Answer 7

Electric current is the flow (movement) of electric charge. The SI unit of electric current is the ampere (A), which is equal to a flow of one coulomb of charge per second.

Answer 8

An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in a plasma.

Answer 9

The amount of electric current (measured in amperes) through some surface, e.g., a section through a copper conductor, is defined as the amount of electric charge (measured in coulombs) flowing through that surface over time. If Q is the amount of charge that passed through the surface in the time T, then the average current I is:
I=Q/T

Answer 10

current .. as in flow .. electrical as in .. flow of electrons passing thru a medium. usually copper wire.. got light bulb?.. need resistance info too?2 types of electrical current. direct current and alternate current.. DC can be lethal.. do not mess w/ DC unless protocols are followed..AC can be lethal too.. all depends on amps being drawn..
