# 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:
$1 \Omega = \dfrac{1V}{1A}$
• 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:
$R = \dfrac{U}{I}$
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:
$R = \rho \dfrac{l}{S}$
where:
• $R$ - resistance of conductor,
• $\rho$ - proportionality coefficient specific for the substance from which the conductor is made,
• $l$ - length of the conductor,
• $S$ - 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.
