# Hertz vs. Ampere

## Difference Between Hertz and Ampere

#### Hertznoun

A unit of frequency equal to one cycle per second. See Table at measurement.

#### Amperenoun

The basic unit of electric current, equal to one coulomb per second and equivalent to the current, flowing in two straight parallel wires of negligible cross section separated by a distance of one meter, that produces a force between the wires of 2.0 × 10-7 newtons per meter of length. The value of an ampere in the International System differs very slightly from that in the meter-kilogram-second-ampere system of units. See Table at measurement.

#### Hertznoun

In the International System of Units, the derived unit of frequency; one (period or cycle of any periodic event) per second. Symbol: Hz

#### Amperenoun

A unit of electrical current, the standard base unit in the International System of Units; colloquially amp. Abbreviation: amp, Symbol: A

*Definition: The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602*

*x 10*

^{−19}when expressed in the unit C, which is equal to A*s, where the second is defined in terms of Δν*

_{Cs}. ([https://www.bipm.org/en/si-base-units/ampere The International Bureau of Weights and Measures])#### Hertznoun

the unit of frequency; one Hertz has a periodic interval of one second

#### Amperenoun

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

#### Hertznoun

German physicist who was the first to produce electromagnetic waves artificially (1857-1894)

#### Amperenoun

the basic unit of electric current adopted under the Systeme International d'Unites;

*a typical household circuit carries 15 to 50 amps*

#### Hertznoun

German physicist who with James Franck proved the existence of the stationary energy states postulated by Bohr (1887-1975)
