translation icon : resistencia
  • You can do like constant current, constant resistance, constant power.
  • low resistance
  • component resistance
  • line resistance

Examples

  • The lower you are, the longer you stay there, the less resistance you get, the faster you are.

  • As explained earlier, the power mesh provides a much lower resistance path than the semiconducting substrate.

    Academic text (1995)
  • So as it gets small, resistance starts to become very, very high.

  • Because this is where you get the best resistance.

  • A resistor has the same resistance at all frequencies if it's perfect.

  • A thermistor is a resistor whose resistance varies with temperature.

  • The material also has a low carbon content that provides resistance to corrosion along welded joints.

    Academic text (1993)
  • In the circuit design, the resistance of the resistor is crucial for controlling the current flow.

  • To ensure optimal performance, the resistance value of each component must be carefully calculated.

  • The technician measured the resistance to determine if the circuit was functioning correctly.

Surface Forms

resistance singular
resistances plural

Morphology

resistance = resist (semi-transparent) = resist + ance

The device sense is an extension from the property 'resistance' (resist + -ance) to a component, which is not the prototypical nominalization and may not be obvious to all learners.

Etymology

Resistance comes from the Latin parts re- 'back' and sistere 'to stand', so a resistor is like something that 'stands back' in the electric path and reduces the flow of current.
