The ampere is the SI unit of electric current and it is one of the seven SI base unitsInterestingly one ampere is approximately equivalent to approximately 6.24×1018 elementary charges such as electrons or holes moving past a given point or boundary in one second.Physicists...
1.(Units) the basic SI unit of electric current; the constant current that, when maintained in two parallel conductors of infinite length and negligible cross section placed 1 metre apart in free space, produces a force of 2 × 10–7newton per metre between them. 1 ampere is equivalent to...

Is ampere a SI unit? Yes, it is. The ampere is identified by the international committee as being the standard unit used to measure current. What is the formula for ampere? To find ampere using a voltameter, first find the surface area of the electrode. Make sure to multiply by 2 to...
The International System (SI) unit of electric current, equivalent to one coulomb (1 C) of electronic charge passing though a point in 1 s (second), i.e., 1 A is equivalent to approximately 6.242 · 1018electrons per second passing through a point.Common abbreviationA.Note 1:The charge ...
The SI prefix "pico" represents a factor of 10-12, or in exponential notation, 1E-12.So 1 picocoulomb = 10-12 coulombs.The definition of a coulomb is as follows:he coulomb, symbol C, is the SI unit of electric charge, and is defined in terms of the ampere: 1 coulomb is the ...
