- The resistivity of a resistor is defined as:
- The SI unit for is .m.
- 26-4 Resistance and Resistivity
- The conductivity of a material is the reciprocal of its resistivity:
- The SI unit for σ is Siemens/m.
- Put pebbles in the hose, increase resistivity ρ, increase resistance R.
- These two devices could have the same resistance
- R, when measured on the outgoing metal leads.
- However, it is obvious that inside of them different things go on.
