   • ▪ the underground movement formed in France during the Second World War to fight the German occupying forces and the Vichy government.
   • 2. the ability not to be affected by something, especially adversely: "some of us have a lower resistance to cold than others"
   • ▪ lack of sensitivity to a drug, insecticide, etc., especially as a result of continued exposure or genetic change: "many insects show resistance to at least one chemical" Similar ability to fight offability to counteractability to withstandimmunity fromdefences againstresilience
   • 3. the impeding or stopping effect exerted by one material thing on another: "air resistance was reduced by streamlining"
   • 4. the degree to which a substance or device opposes the passage of an electric current, causing energy dissipation. By Ohm's law resistance (measured in ohms) is equal to the voltage divided by the current.
   • ▪ a resistor or other circuit component which opposes the passage of an electric current.

   Word Origin late Middle English: from French résistance, from late Latin resistentia, from the verb resistere ‘hold back’ (see resist).

   3 days ago · Electrical resistivity (also called volume resistivity or specific electrical resistance) is a fundamental specific property of a material that measures its electrical resistance or how strongly it resists electric current. A low resistivity indicates a material that readily allows electric current.

   What does resistance mean in physics?

   • Resistance could be defined as the measure of the opposition that is offered to the flow of current in a particular electrical circuit. This quantity is measured in Ohms which is also its SI unit and is given by Greek letter omega (Ω) ( Ω). We could classify materials into conductors and insulators by the resistance offered by them.

   What is the unit of resistance?

   • The unit of resistance is the ohm. In the metre-kilogram-second (mks) system, the ratio of area in square metres to length in metres simplifies to just metres. Thus, in the metre-kilogram-second system, the unit of resistivity is ohm-metre. If lengths are measured in centimetres, resistivity may be expressed in units of ohm-centimetre.

   What is the difference between resistance and resistivity?

   • Both resistance and resistivity describe how difficult it is to make electrical current flow through a material, but unlike resistance, resistivity is an intrinsic property and does not depend on geometric properties of a material.

    Jun 18, 2024 · Resistance is an intrinsic property of a material and is determined by the type of material and its structure. Materials with high resistance, such as rubber and glass, are poor conductors of electricity, while materials with low resistance, such as copper and silver, are good conductors of electricity.
