It is a property of a material that quantifies how easily current can conduct through the material. How hard it is for electrons to move through the circuit. Resistance is measured in a unit called the ____ electrical power.

Electrical resistance is also known as specific electrical resistance. The SI unit of resistance is ohm which is defined as a volt per ampere. Resistance is measured in units called ohms represented by the Greek letter omega Ω.

The basic unit of resistance measure. Resistance is measured in ohms kilo-ohms and is denoted by symbols ῼ or kῼ. Named after Georg Ohm back around 1830 give it take.

Rub the balloon against the sweater. Answer 1 of 10. It is measure in Ohm-meter.

Its the amount of resistance required to allow one ampere of current to flow when one volt of potential is applied to the circuit. ρ R Al. Following is the formula of electrical resistivity.

A ampere b coulomb c volt d watt e ohm. Resistance is opposition to current where current is the flow of charge. A wire is said to have a resistance of one ohm If the one-ampere current is passed through it.

One ohm is equal to the resistance that allows 1 ampere. Named after the German physicist and mathematician George Simon Ohm. ρ Ω-m Ohm-meter According to the equation the resistivity of a material is the resistance offered by a material having area of 1 m2 length of one meter.

The larger resistance the greater the barrier against the flow of current. The resistance shows the relation between the applied voltage and the flow of charges. Some of the popular units of resistance include Abohm megohm statohm preece and planck-impedance.
