How to use Ampere in a sentence as a noun

A common bond wire diameter is 1 mil, which, depending on length, can reliably handle a bit more than an ampere without fusing.

Hit with a 300-ampere GIC, a high-voltage transformer's paper tape insulation will burn, its copper winding will melt, and the transformer will fail, either right then and there or in the future.> There is a quick and relatively cheap fix to help protect these transformers from geomagnetically induced currents: They can be retrofitted to block the inflow of GICs.

This is the same amount of energy in passing a one ampere current of electricity through a resistance of one ohm for one second.

If that were the case, we'd need separate codepoints for every letter used as a unit of measurement, from A for ampere onwards.

I feel quite stupid, but I just can't parse the following:"At present, an ampere is defined as the amount of charge flowing per second through two infinitely long wires one metre apart"If the wires are one metre apart, then how are they infinitely long?

If a given number of electrons produce the same quantity of H using two different methods, that means the yield is related to current, and is the same for both methods, ampere for ampere.

"In fact, of the seven fundamental metric units — the kilogram, meter, second, ampere, kelvin, mole, and candela — only the kilogram is still dependent on a physical artifact.

I mean, it seems more natural to think of amperes and coulombs per second rather than to define coulombs as the amount of charged carried by a 1 amp current in 1 second.

Ampere definitions


a former unit of electric current (slightly smaller than the SI ampere)


the basic unit of electric current adopted under the Systeme International d'Unites; "a typical household circuit carries 15 to 50 amps"
