Measurement of resistance

Measurement of resistance

Measurement of resistance- Properties of resistance plays an important role in determining performance specification for various circuit elements including coil, winding, insulation etc.

Apart from this resistor are use as standard for measurement of other unknown resistances and for the determination of unknown inductance and capacitance.

For the point of view measurement of resistance are classified into three categories-

  1. Low resistance (<1 ohm)
  2. Medium resistance (1ohm<R<100K ohm)
  3. High resistance (> 100K ohm)

There is one method for measurement of low resistance.

  • Kelvin’s double bridge

There are four methods for measurement of medium resistance.

There are four methods for measurement of High resistance.
