Resistance

The act of resisting; opposition, passive or active.

The quality of not yielding to force or external pressure; that power of a body which acts in opposition to the impulse or pressure of another, or which prevents the effect of another power; as, the resistance of the air to a body passing through it; the resistance of a target to projectiles.

A means or method of resisting; that which resists.

A certain hindrance or opposition to the passage of an electrical current or discharge offered by conducting bodies. It bears an inverse relation to the conductivity, -- good conductors having a small resistance, while poor conductors or insulators have a very high resistance. The unit of resistance is the ohm.

A material's opposition to the flow of electric current

(psychiatry) an unwillingness to bring repressed feelings into conscious awareness

the degree of unresponsiveness of a disease-causing microorganism to antibiotics or other drugs (as in penicillin-resistant bacteria)

(medicine) the condition in which an organism can resist disease

a material's opposition to the flow of electric current; measured in ohms

the capacity of an organism to defend itself against harmful environmental agents; "these trees are widely planted because of their resistance to salt and smog"
