Are cursor.size() and cursor.count(true) equivalent?

How do I find the resistivity equivalent to a circuit?

  • Answer:

    Resistivity is a property of materials, like density and color. You can measure it in a material sample, but you can NOT get the resistivity of a circuit. The concept is meaningless. Conductance is the inverse of resistance, and is something you can measure in a resistor. conductivity is the inverse of resistivity, and these you can measure in a material, like copper or iron. You do it by measuring the resistance end to end of a sample of the material and using the dimensions and the resistance to calculate the resistivity. R = ρL/A or ρ = RA/L ρ is resistivity of the material in Ω-m L is length in meters A is cross-sectional area in m² .

Resistivity is a property of a material. It is measured in ohm-cm or ohm-m. Resistivity of a piece of material is the Resistance times its area / length.
