An ampere is the unit of (electrical) current.
An ampere hour (A.h) is a non-SI unit of measurement for electrical charge (the SI unit is a coulomb-which is equivalent to an 'ampere second'). So an ampere hour is equivalent to 3600 coulombs.Cells and batteries are generally rated in terms of ampere hours, as a convenient alternative to the kilocoulomb.
As an ampere is an SI base unit, it is NOT defined in terms of the coulomb. In fact, it is defined in terms of the force (in newtons) between two, parallel, current-carrying conductors. The coulomb, being an SI derived unit, is equivalent to an ampere second.
Liken volt and amp to a water in a pipe. Voltage is the water pressure in the pipe and amperage is the water flow through the pipe. They are two completely different electrical units.
The SI convention is that all SI units, when written in full, are written entirely in lower-case letters. For those units named in honour of individuals, only their symbols are capitalised. For example, the SI unit for power is written as watt but, because it is named in honour of James Watt, its symbol is a capital W.So it is incorrect to capitalise ampere (not amp!).
An Electric PathA complete path for an electric current to follow is called a closed circuit. Ampere is the SI unit for measuring an electric current.
Ampere is the basic unit of electrical current.AnswerThere are, in fact, two answers. The ampere is the SI Base Unit for electric current, but it is also the SI Derived Unit for magnetomotive force.
ampere
Its SI unit is Ampere metre or Am.
Ampere (A)
Yes, the ampere is an SI base unit, one of the seven, and equals the passage of a Coulomb of charge per second. Its official definition has to do with force between current carrying wires though.
ampere
The SI unit of electric current is the Ampere.

Ampere is the SI unit of electric current.
The SI unit of electric current is the ampere. While it is an SI base unit, it can also be considered to be a combined unit, coulombs per second.
The ampere is the SI base unit for electric current, and is defined in terms of the force between two parallel conductors due to the interaction of their magnetic fields.
Ampere, milliampere, microampere, nanoampere, picoampere.
