What unit is represented for coulomb per second?
The ampere is one of seven SI base units, and is defined in terms of the force it produces between two, parallel, current-carrying conductors. It is incorrect to say that an ampere is 'defined' as a coulomb per second, although it is certainly 'equivalent' to a coulomb per second.The coulomb is a SI derived unit, and is defined in terms of the ampere and the second. In fact, it is a special name given to an ampere second.
Why ampere considered as a fundamental unit though it is a derived one?
Because you have to start somewhere - you can't derive ALL units. You have to have SOME fundamental units.For example, 1 ampere = 1 coulomb / second. That also means that 1 coulomb = 1 ampere x 1 second, or that 1 second = 1 coulomb / 1 ampere. In other words, you can derive any of the three units from the other two. In practice, for base units, units were chosen that can be measured with great precision.Another AnswerThe ampere is not a 'fundamental' unit; it is a base unit. The ampere was chosen as a base unit, because it relates electrical units to mechanical units, being defined, as it is, in terms of the force (which itself is defined in terms of base units) between current-carrying conductors.You might be getting confused because, quite wrongly, the ampere is often defined as a 'coulomb per second'. While it is certainly equivalent to a coulomb per second, it is not definedin this way.
How is a coulomb used to define 1 amp?
1 coulomb per second = 1 amp.Note "coulomb" is the NUMBER of electrons....... "amps" is a measure of flow.AnswerAn ampere (not 'amp') is not defined in terms of coulombs, but in terms of the force between two, parallel, current-carrying conductors due to the interaction of their magnetic fields. However, an ampere is equivalent to (but not defined as) a coulomb per second.
How is current fundamental physical quantity when current is equal to charge per unit time?
The unit is the Ampere, equivalent to 1 coulomb of charge per second.
How much charge flows in a pocket calculator for each minute when the current is 0.0001 ampere?
0.0001 ampere means 0.0001 coulomb per second(0.0001 coulomb per second) x (60 seconds per minute) = 0.006 coulomb per minuteregardless of where the current is flowing or in what kind of device.

What is dimensions of coulomb?
Current is rate of flow of charge, so 1 ampere = 1 coulomb per second. As ampere and seconds are both fundamental units (and coulomb is derived), a coulomb has the dimensions [current][time] i.e. As

One ampere is equivalant to?
1 Coulomb per second.
What kind of electrical unit is coulomb?
A Coulomb is the unit of charge. It is a fundamental unit, representing the number of elementary charges (typically, electrons) available to do work. Its numerical value is about 6.241510x1018 elementary charges Important combined units based on the coulomb are the ampere, which is coulombs per second, the volt, which is joules per coulomb, and the volt-ampere, which is joules per second, or watts.
Unit of measurement for electromotive force?
emf has SI units of volts, equivalent to joules per coulomb.

How can you define temperature in terms of mass and length and time?
All units can be decomposed into the fundamental units of mass, length, and time. Some would also add the fundamental unit of charge, which used to be the coulomb but is now, I think, the ampere1. For example, the watt is a joule per second; the joule is a newton-meter; the newton is a kilogram-meter squared per second squared2. You will have to do a similar decomposition of a Kelvin (or a degree Celsius or Fahrenheit). 1. The ampere was once defined as one coulomb per second. But now I think the coulomb is defined as an ampere-second. 2. The unit of force is the newton, F = ma, and the units for acceleration are meters per second squared.
What is the SI unit for the electric charge?
The Coulomb. If 1 Coulomb is transmitted per second this is 1 Ampere
How is current fundamental physical quantity when current is equal to charge per unit time?
The unit is the Ampere, equivalent to 1 coulomb of charge per second.
What is the value of one ampere?
The ampere is defined in terms of the force between two, parallel, current-carrying conductors.A current of one ampere flowing for one second will transport a charge of one coulomb. So a coulomb is an ampere second. Transposing this confirms that an ampere is equivalent to (not 'defined' as) a coulomb per second.
What si 10 microamperes in volts?
A microampere is a unit of current in micro coulombs per second, while a volt is a unit of electrical pressure in joules per coulomb. The two units are not convertible.
