Some facts#

  • Electric current is ordered directional movement of electric charges.
  • Most often when we talk about electric current we mean electron motion, but it can also be other particles having a charge (both positive and negative) e.g. ions or protons.
  • The electric current is defined as the ratio of electric charge that moved through the point of the conductor to the amount of time passed.
  • Simply speaking, the current tells us how fast (or with what intensity) electric charges are moving (flowing). Mathematically, we can write it in the following form:
    Iavg.=ΔqΔtI_{\text{avg.}} = \dfrac{\Delta q}{\Delta t}
    where:
    • Iavg.I_{\text{avg.}} - average current during the measurement,
    • Δq\Delta q - the electric charge moved during the measurement,
    • Δt\Delta t - time of measurement
  • In the case when the number of transferred charge can change in time, it is necessary to introduce the concept of instantaneous intensity defined as charge derivative over time (→ see derivative of the function):
    Iinst.=dqdtI_{inst.} = \dfrac{dq}{dt}
  • The basic unit of current is one ampere (1A). The current of one ampere is equivalent of one coulomb moved during one second:
    1A=1C1s1A = \dfrac{1C}{1s}
  • The current flowing through the conductor depends on the applied voltage (potential difference beetwen the ends of the conductor) and also on resistance of the conductor. In the case of linear elements, the current can be calculated using Ohm's law.
  • The device used to measure the electric current is ammeter.

How to convert#

  • Enter the number to field "value" - enter the NUMBER only, no other words, symbols or unit names. You can use dot (.) or comma (,) to enter fractions.
    Examples:
    • 1000000
    • 123,23
    • 999.99999
  • Find and select your starting unit in field "unit". Some unit calculators have huge number of different units to select from - it's just how complicated our world is...
  • And... you got the result in the table below. You'll find several results for many different units - we show you all results we know at once. Just find the one you're looking for.
