Measured in ohms
WebIt is measured in ohm-meters or Ωm and is denoted by the Greek letter ρ. Factors affecting resistivity Temperature. Resistivity grows with temperature because the temperature is a measure of the average kinetic energy of the particles of a material. WebCapacitive Reactance. Capacitive Reactance is the complex impedance of a capacitor who’s value changes with respect to the applied frequency. Unlike resistance which is not dependent on frequency, in an AC circuit reactance is affected by supply frequency and behaves in a similar manner to resistance, both being measured in Ohms.
