Some facts

  • Resistance defines the relation between applied voltage (electric potential difference) and the electric current, that flows through the conductor.
  • Simply speaking: the greater resistance, the greater voltage should be used to reach the same current.
  • The basic unit of resistance is one ohm . A resistance of this value corresponds to a conductor through which, after applying 1V (one volt), a current of 1A (one ampere) will flow:
    1Ω=1V1A1 \Omega = \dfrac{1V}{1A}
  • In order to measure the codnductor resistance experimentally, we can apply a known, constant voltage to it, and then measure the flowing current. Then the voltage to current ratio will be equal to the resistance of the examined conductor:
    R=UIR = \dfrac{U}{I}
    where:
    • R - resistance of the conductor,
    • U - voltage applied to the conductor,
    • I - current that flows through the conductor after applying voltage.
  • Resistance is a specific to given conductor. If we have a conductor with a constant cross-sectional area (e.g. an electric cable of known thickness), its resistance can be described by the following equation:
    R=ρlSR = \rho \dfrac{l}{S}
    where:
    • RR - resistance of conductor,
    • ρ\rho - proportionality coefficient specific for the substance from which the conductor is made,
    • ll - length of the conductor,
    • SS - cross-sectional area of the conductor.

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.
