  • noun the ability of an organism not to be affected by something such as a disease, stress factor, process or treatment


  • noun the opposition of a body or substance to current passing through it


  • noun opposition felt or shown by people to something


  • 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 R. Also called electrical resistance.
  • 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.

  • A region of an asset's price where selling has or is expected to emerge that will often provoke a market reversal to the downside. Many forex traders that base their trading decisions on technical analysis will regularly assess the resistance levels in the exchange rate for a currency pair before establishing a position or placing an order.
