1 Ampere = 1 Coulomb per second
0.25 A = 0.25 Coulomb per sec
1 minute = 60 seconds
20 minutes = (20 x 60) = 1,200 seconds
0.25 A for 20 minutes = (0.25 x 1,200) = 300 Amp-seconds = 300 Coulombs of charge
we have
I = q/t
or
amount of electric charge
q = I.t
here
I = current = 0.2 A
t = time = 1hr = 3600 s
so,
q = 0.2 x 3600
thus,
q = 720 C
A current of 0.2 A, over a period of one hour, represents a flow of electric charge of 720 Coulombs.
1 ampere = 1 coulomb per second
0.2 amperes = 0.2 coulombs per second = 720 coulombs per hour
That is called electric current, or simply current.
Electric current is electric charge in motion. Most electric charge is carried by the electrons and protons within an atom and is affected by conductivity of elements ie copper.
Rate of flow of charge is called electric current. Generally we knows current means flow.... here rate of flow of charge means how much charge flows in a given time is called electric current
direct current
electric current
If you know the electric current, the flow of electric charge through an object, traveling through a circuit and how long the current is applied, you can calculate electrical charge using the equation for current Q = It in which Q is the total charge measured in coulombs, I is current in amps, and t is time that the ..
That is called an electric current. Actually, defining an electric current as a "movement of charge" is a little simplistic, but movement of charge is certainly an important part.That is called an electric current.

Current is the flow of electric charge or the rate of the flow of an electric charge through a conductor.
Electrons are called electric charge. They are responsible for electric current.

It is called an electric current.
Electric Current is the flow of electrons and hence charge
That is called electric current, or simply current.
The charge transferred in 25 minutes by a current of 500 mA is 750 coulombs. Amperes is defined as coulombs per second, so 500 mA is 0.5 coulombs per second. 25 minutes is 1500 seconds, so the charge is 750 coulombs.
Electric current carries electric charge. Actually to say it in the right sense, we have to say that electric current is the rate of flow of electric charges
Electric current is electric charge in motion. Most electric charge is carried by the electrons and protons within an atom and is affected by conductivity of elements ie copper.
