The electrical resistance of an electrical conductor is the opposition to the passage of an electric current through that conductor. The inverse quantity is electrical conductance, the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with the notion of mechanical friction. The SI unit of electrical resistance is the ohm (Ω), while electrical conductance is measured in siemens (S).

The quality of a driver due to which it flows through it Resists the flow of current, called electric resistance of the conductor. Display it with R. If there is a potential V voltage between the ends of a driver and the current flows in the conductor. If the ampeier, then the resistance of the driver

is a scalar amount. It is a single voltage / ampere or ohm). If a conductor has 1 ampere electric current and electric potential difference between the two ends of the conductor is 1 volt, then its electrical resistance is 1 ohm.


Very large resistance is expressed in mega-ohm and very small resistance is expressed in micro-ohm.



1 megoma = 10 ^ 6 ohm


1 microom = 10 ^ - 6 ohm
