resistance

- The opposition a material offers to the flow of current, with the concomitant conversion of electrical energy into
__heat__energy. Resistance may be intentionally introduced into a__circuit__, for instance, for__current regulation__or for__voltage regulation__. In an__AC circuit__, resistance is the__real number__component of__impedance__. Expressed in ohms, or fractions/multiples of ohms. Its__symbol__is. Also called electrical resistance.*R* - A specific resistance (1)
__value__, such as that of a__conductor__, component,__circuit__, or__device__. Also called resistance value. - The
__real number__component of__acoustic impedance__. Expressed in acoustical ohms. Also called__acoustic resistance__. - The capability or
__extent__to which a material or__body__can withstand something. For example, abrasion, impact, or__heat resistance__. - symbol R
