# 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.
